How Thick a Branch Will It Really Cut? Sizing Up Seesii's Cordless Mini Chainsaw for Pruning Branches UK
Your loppers give up long before the branch does. A petrol chainsaw is overkill, and for a lot of people it is plain frightening. Seesii's 1.4kg mini saw sits in that gap, and its buyers are very clear about both what it flattens and the one part you will be re-tensioning every few cuts.

Seesii's bullet points say this saw "slices through branches up to 6 inches thick in seconds". The photo halfway down the same listing is selling something quieter: prune 100+ 4-inch branches, 80 minutes of running. And Harry Hill, three stars, says the instruction leaflet in his box warned him off anything thicker than 2cm, a gap he calls "somewhat contradictory" before asking, "is this misinformation and should be clarified".
Three numbers, one product. Meanwhile 8,249 buyers have parked it on 4.5 stars, so plainly something here works. The last 100 reviews are unusually specific about where the real cutting line falls, and unusually united about the one part of this saw that is going to annoy you. Both answers are below, along with the item in the product photos that a lot of buyers say never turned up in their box.
Six Inches on the Bullets, Four Inches on the Box
Start with what Seesii claims, because the claims do not agree with each other.
The bullets promise a 1000W pure copper motor cutting branches up to six inches thick, "three times faster than manual tools". The bar is stamped 6 inch, and a listing graphic pairs a 23ft/s chain speed with a badge saying a six-inch cut takes about seven seconds. Scroll one image further and the marketing goes quiet: "Prune 100+ 4-Inch Branches", "80 Minutes of Running". Four inches, not six. That is Seesii's own art department hedging.
Six inches is the bar length, the geometric limit of what you can pass a chain through in one cut. It is not a recommendation. Four inches is the number the company was happy to put a "100+" claim next to. Hold on to both.
The one number the reviews back up is the runtime. Two 21V 4.0Ah packs, each with a four-bar charge indicator on the body, and buyers treat the 80-minute claim as fair. Morris, five stars, says the batteries "last a long time (there are two in the pack)". Suzanne calls it a "Really good budget saw. Works well and battery life is pleasing". One buyer who spent a full day pruning swapped to the second pack and found the first had recharged "within the hour". If you have ever run a single-battery saw flat halfway up a hedge, that spare pack is the point of this kit.
One caveat before any cutting claim below, mine included. Amazon pools this listing's reviews across bar sizes: at least two five-star reviewers are clearly talking about the 8-inch Seesii, one of whom names it outright. Where a quote comes from an 8-inch buyer, I flag it.
How a Cordless Mini Chainsaw for Pruning Branches Behaves in a Real UK Garden
Seven of the hundred reviews reach, independently, for the same simile. Matthew: "It's very fast for its size it's like a hot knife through butter". tracy vincent: "Cuts through saplings like butter". Edward Joseph Leavy, A. Pearce, Jummy and two others all land on butter unprompted. Whatever else is true here, the first cut converts people.
The useful question is where the butter stops, and the reviews answer it far more precisely than the listing does. Ed Doyle, five stars, gives the cleanest version: "For pruning 2 - 4 inch branches, it's like a hot knife in butter. It'll tackle bigger jobs too, but with extra care of course." He mentions almost in passing, "I just cleared 10 leylandii with it!"
Push past that range and the tone shifts. Eyma Del Mar, also five stars, is blunt about the trade: "it cuts through 2inch branches with ease, it will cut through bigger, but its not happy about it, so be careful or you could burn the motor out". Patrick in Co Down found it "cut trough branches 4-5 inches thick without too much bother" (sic), which is about as high as the credible reports go. Robbie's "Made light work of an 8inch diameter tree" is the outlier, and worth treating with caution given the pooled reviews.
So: two to four inches is where this saw is happy. Four to five is doable if you are patient and let the chain do the work. Six is the bar, not the job.
Framed that way it is a lopper replacement, not a shrunken felling saw. Mr M D Venning bought his for "cutting sticks that are too thick for the secateurs". Another five-star buyer calls it "Excellent for garden tidy ups where a lopper is just not up to the job, this makes easy work of it." Banjoe Bob sets the ceiling in one line: "Please remember it is not a full chainsaw so won't cut trees!" And a three-star sceptic gets a hearing: "Alright for small stuff, but not big enough to handle cuts that can't easily be done with a good hand-saw anyway."
Inside that range, people are getting through real work. ired brought a hedge down "from 15 feet to 5 feet". Kimberley used hers "hacking down an old treehouse". Amjid Ali lost a pear tree, "was given a quote of £400", bought this instead and "had the tree all cut up and ready for the tip within a few hours". Morris has "Dispensed with my larger STIHL petrol chainsaw" altogether.
The Chain Is the Catch, and It Comes Up Nine Times
Buy this saw and you buy the chain problem with it. Nine of the hundred reviews mention the chain coming loose or needing re-tensioning. Eight treat it as a fault. The ninth treats it as the job.
Mr. Tom Mckerrow docked a star and said why: "Chain needs constant tightening, hence the four stars." Anne Richards found that "when the chain slips it's very fiddly to get back the tension. Perhaps mine is faulty?" On the evidence of the other eight, it probably was not. Jummy's chain "came off a few times & awkward to re fit ( need 3 hands )". Mark Ramsey, two stars, gave up: "the chain tension is poor as is the adjustment".
Simon S. is the most useful of the lot, because he describes the whole loop. Leaves and small branches pack in under the side cover, so you pull the cover off to clear it, and then "you then can spend 15 - 20 mins trying to get cover and chain tension to line up to fit cover". His summary: "you have to contently adjust the chain tension" (sic). Patrick in Co Down saw the same thing and shrugged it off: "The chain came off a few times when debris got clogged in the mechanism but it was fairly easy to get it back on."
The ninth review is the one that matters. Ed Doyle, five stars: "Does require a little bit of care, regularly oiling of the chain during use, and similarly checking and adjusting chain tension." That sentence is the difference. Owners who treat re-tensioning as part of running a chainsaw stay happy with this thing. Owners who expected a sealed appliance that never needs a screwdriver do not.
Two related warnings. steve evans got a saw that "Arrived with chain fitted wrong way round", and Mr. Peter J. found the leaflet and the guide-plate diagram disagreed about which way the chain should face. Check it against the markings on the bar before your first cut, battery out. And order replacement chains on Amazon rather than from the maker: Alexander Penney's four-star review is mostly a shout for help, in capitals, "ANYONE KNOW WHERE TO GET NEW CHAIN? THE SEESII WEBSITE IS NOT WORKING." There is one spare in the box. Look after it.
There Is a Bottle of Oil in That Photo. Buyers Say It Was Not in Theirs.
Look at the kit photo: hard case, gloves, spare chain, screwdriver, the bolt-on front handle, two batteries, and a small bottle of chain oil. The bullets add safety goggles.
Now read the reviews. Oil comes up in fifteen of the hundred, and nine of those say, one way or another, that you need to buy it yourself. Mr. Peter J. is sharpest on it: "no chain oil is provided although there is a misleading picture showing oil being filled into the oil contained within the unit". Discerning Shopper, five stars and clearly experienced, tells buyers plainly, "Please note that you will need to purchase chainsaw oil separately, which is standard practice for maintenance." Susan McCulloch: "Should have ordered the chain saw oil at the same time !" Patrick picked a bottle up "from screwfix for just under £6.00." Bidski's entire review title is "Don't forget the chain oil".
Box contents do change over a product's life, and the bottle may be a recent addition. Either way the safe move is the same: add chainsaw bar oil to the order. It costs very little, and the saw is unusable without it.
Then there is the reservoir. Seesii's own image labels it a "1 oz Oiler", roughly 30ml, fed by pressing a button with your thumb. That is a tiny tank to pair with an 80-minute battery, and it shows. UK-Prime, still five stars, notes the "oilers always leaking and make a mess in the box". A four-star buyer's only gripe is that "you have to drain oil out of tank after use , minor negative". Terry, three stars, abandoned it: "the oil tank is virtually useless and I have to add oil by hand".
Take the hint from all three. Empty the reservoir before the saw goes back in its case, and top it up as you work rather than filling it and hoping.
Five One-Star Reviews, One Ending
Every one-star review in this sample of 100 finishes the same way: the saw stopped working.
Rory Wheatley: "Broke after a month so can't return it". Barry's review runs to two lines, "2 months old.." and "Broken." Graham: "Poor, broke during first proper use." P M. logged the full sequence, chain loosening first, then "Motor constantly cuts out." And one buyer whose name is not displayed reports it "just cuts out over and over. The little engine overheats".
That last complaint is a pattern in its own right: four reviews describe the motor cutting out mid-job. Terry says it "tends to overheat very quickly and cuts out after less than 10 seconds of use". Charles M, three stars and more than a year in, worked out what was probably happening: "It starts off OK, not the most powerful, but acceptable. And then it cuts out." Swapping the battery seemed to revive it, but he was not convinced: "I suspect the battery change is coincidence and it actually is a heat trip, and starts when cool again." He is very likely right. A 1000W motor in a 1.4kg body has nowhere to dump heat, and Eyma Del Mar's five-star warning fits: force it through wood it dislikes and "you could burn the motor out".
The uncomfortable detail is the timing. Two of those five one-star buyers say the failure arrived after their return window had shut. So did a four-star buyer, M&A, and this is where the story turns: "While it was just past the return date, the manufacturer saw my initial review and responded immediately, issuing a refund." Mr S M Moffitt's saw broke at four months and he contacted "customer services, who helped me through my Amazon account, as the Chainsaw has a 12 month warranty". The replacement arrived "within 7 days". Maybee's battery stopped taking charge after just over a year, and Seesii sent a new one "without any quibble".
So there is a twelve-month warranty and, on this evidence, a company that stands behind it. One condition: go through Amazon. Mr. Peter J. tried the contact details supplied in the box and got nowhere. "I emailed Customer Support on the email provided but it was returned undelivered. I rang the telephone number provided but the woman had never heard of the Sees Company."
Practical advice, then. Give this saw the hardest jobs you bought it for inside the first thirty days. If it is going to fail, you want it to fail while sending it back is still easy.
The Gardeners Who Would Never Touch a Petrol Chainsaw
Seesii says the quiet part out loud. One of the listing images reads "One-Handed Operation. Suitable for Women, Elderly. 3.1 Lbs." It is blunt marketing, and the reviews back it up harder than most marketing ever gets backed up.
audrey, five stars: "I'm 65 yrs female and delighted this is very light weight with battery easy to engage/disengage." M. Sulaiman titled her review "All Lady gardeners should have one." and says it made her work "in the garden and my allotment so much easier". One review, marked helpful by nine other shoppers, lands hardest of all: "no more struggling with secateurs or waiting for my husband", from a buyer who admits "It took me 2 weeks to pluck up the courage to get it out of the box, but now there is no going back."
Danielle, five stars, sums up the category, though note she is reviewing the 8-inch version of this listing: "I bought the SEESII 8 Inch Mini Cordless Chainsaw because I don't feel comfortable using a full-size chainsaw, and this has been an excellent alternative."
Seesii lists 1.4kg. Eyma Del Mar notes that "the battery makes it a little heavier", and a 4.0Ah pack is a real lump on the end of your wrist. Even so, one buyer spent a day pruning a large tree and could "hold on to ladder, tree whilst sawing as was light enough", which is exactly the job a full-size saw rules out.
One warning for left-handers. A four-star buyer found the safety button "fine using your right hand thumb but extremely awkward if not impossible using your left hand thumb", while bladerunner, five stars, reports it is "Easy to use left or right handed." They disagree, which probably means it comes down to your hand. If you are left-handed, work the safety lock a few times before committing to a season of pruning with it.
Respect It Like a Chainsaw, Because That Is What It Is
Banjoe Bob is right that this is not a felling saw. It is still a chainsaw, with a chain Seesii says runs at 23 feet per second, and it will do to a finger what it does to a branch.
AngelxBabyx, four stars, had been using hers for about a month: "Its pretty decent but definitely dangerous. Husbands nearly had a few injuries and he knows what hes doing." Ross Morrow, five stars, is enthusiastic and emphatic in the same breath: "this little saw is extremely powerful, and if not treated with the same respect you should have for any Chainsaw, will go through anything!" Jack lambert, who signs off "I'm just a gardener", wraps a warning inside his five-star recommendation: "be very careful they are very powerful as you will find out".
The safety gear in the box is a tick-box exercise. JAMES RAMSDEN, five stars, is funny about it and entirely serious: "I got some better gloves, the ones that come with it I wouldn't trust so much if was to saw my finger off." Discerning Shopper goes further: "I also highly recommend investing in better quality safety gear, specifically gloves and a mask." Buy proper chainsaw gloves and real eye protection, and treat what arrives in the box as packaging.
Two things in the box do help, and plenty of buyers seem to leave them unused. There is a sturdy front hand guard that keeps sawdust and splinters off your knuckles, and a detachable auxiliary handle that screws onto the front of the housing and turns this into a two-handed tool. Fit it. JG, four stars, puts it plainly: "Be sure to use both hands to support saw when using. It's safer." The screwdriver you need is already in the box.
Buy It for the Four-Inch Jobs, Not the Six-Inch Ones
The lifetime score is 4.5 stars from 8,249 ratings, and the 100 most recent reviews average exactly the same 4.5. That is worth more than it sounds. Plenty of cheap tools coast along on an old reputation while recent buyers quietly turn on them, and this listing has not slipped.
What you are buying is a 1.4kg saw that walks through the jobs your loppers stall on, a second battery so you never have to stop, and a hard case that keeps the whole lot together. Between two and four inches, in green wood, it is superb, and those seven independent butter comparisons tell you how it feels on the first cut.
What you are accepting is a chain that needs re-tensioning, a bottle of oil you should order alongside it, a reservoir that weeps if you leave it full, and a small but real chance of a failure that surfaces after month one. The twelve-month warranty and Seesii's Amazon-side service take some of the sting out of that last one, but stress-test the saw early anyway.
Skip it if you want to fell trees, if you will not pick up a screwdriver, or if you expect a sealed appliance that asks nothing of you. Buy it if your loppers have started losing arguments with your hedge and a petrol saw is more machine than you want in the shed. That gap is exactly where this thing lives, and it is why 73 of the last 100 buyers gave it five stars.
Check today's price on Amazon, and order a bottle of bar oil while you are there. See the Seesii mini chainsaw on Amazon.
