I have had this for a few days and have broken it in. As the owner of a large chainsaw 3.5hp 50cm, this small one with 1.34hp and a narrow (curving) blade is gearless, the specific one being 25cm, it runs like a train, it is powerful and has nerve, of course after the break-in: {in the first 1 liter of fuel + 25ml of oil ((for two-stroke!!)) (it gives about 3-4 refills) and relaxed cuts on branches, without full throttle with quite low revs just before the chain starts to turn to lubricate the cylinder. In the second liter 26ml of oil and then forever 25ml per liter that is 1:40 in 5 liters of fuel is 125ml of oil}.
It starts very easily, cuts everything, it is dual-purpose and the chain DOES NOT loosen easily after several hours of cutting ((be careful because it doesn’t have gears the first time lubricate with chain oil a few drops, in the groove of the blade and open the oil pump adjustment, from below to max (the screw only turns 90*!! don’t force it, it doesn’t release coins) until the pump raises oil, then after it will lubricate enough turn it back to min the amount of oil is just fine)).
Don’t tighten the chain too much so it doesn’t turn... the chain should be able to turn with a little force by hand (this because I saw in the comments that some burned the blade).
The machine is euro5 and doesn’t smell like two-stroke, it has low consumption.
Something that impressed me positively is that it doesn’t heat up and cools down quickly, during a pause I made to fill it with chain oil and fuel it takes 5-15 seconds to warm up.
The idle from the factory is a bit high for my taste, so I lowered it a bit so it doesn’t make so much noise and consumes at idle.
In a few more tanks, the choke will also go (the metal one under the filter (makes it softer, quieter, and more relaxed on the throttle)) - it doesn’t have weather temperatures < -0-, for better breathing (a bit more nervous and more revvy) and the carburetor will be adjusted with special screwdrivers, (!!!if you are not sure how to adjust the carburetor and don’t know don’t mess with it!!!) consult someone with experience.
The chain it has is very good, cuts dense sawdust and is wild so it doesn’t need pressure.
From what I read with a blade with bearings - gears it is a rocket, so at some point it is in immediate upgrade.
After 10 liters of fuel change the stock spark plug with DENSO or NGK.
It is well-balanced even when full of fluids, comfortable and easy to use.
The cost of everything I describe does not exceed 25-45 euros and makes the machine better than the pruners of 300+ euros.
After almost daily use and cutting and chopping several tons of firewood (it has also cut several logs because I was too lazy to carry the big one) I have to say that the stock chain is very durable, doesn’t dull easily, cuts both hard dry and burnt wood very easily, I even got a second identical spare and still haven’t changed it.
The machine after the break-in had the Chinese spark plug changed, it is a pleasure, it has no temperature issues, I happened to work it for 3.5 continuous hours only stopping to add fuel oil for at most 4 minutes, and both the plastics and the exhaust were normal. Of course, I clean it daily with a cloth and a brush for the ventilation holes.
The blade on the logs, the letters faded but that’s reasonable, however, it didn’t catch fire or bend, etc.
One positive that is not mentioned anywhere, except in the instructions, and I have tried it as well, is that if the blade hits (hard) for example from a falling branch, trunk, or the chainsaw falling, the chain brake automatically engages.
Be particularly careful!! It is relatively dangerous (for the left hand), compared to the "classic" chainsaws where you always have both hands on the machine. It is also very agile (you can make movements easily and need to be careful not to touch, for example, your leg, hand, etc.), so for a beginner who does not have relevant experience with standardized movements, I would not recommend it.

The machine has only changed one spark plug from the Chinese one to NGK and one air filter. It has paid off its money from the first 20 days... after so long it has eaten 3 new Nakayama chains which lasted me 3 days at most and then every time I had to sharpen it on the machine...
A month ago I got this Hyundai HSC08 Chainsaw Chain with a Pitch of 1/4", Guide Thickness of .050"-1.3mm & Number of Links 60E for 10E out of curiosity... and a new blade this Oregon Single Rivet Chainsaw Blade 25cm (10") for Chain with a Pitch of 1/4", Guide Thickness of .050"-1.3mm & Number of Links 58E for 18E... it works every day on dry pieces and large trunks (photo) and still cuts wild (I haven't sharpened it to see when it will dull) with Visco Parts V-45 Chain Oil 4lt. I don't know if it's just the chain or the whole set that I changed, but the machine is a pleasure.

The machine, after so much wood, literally broke one spring from the clutch....(photo) spring cost under 1.5 euros and the cost of a new complete clutch is 9-10 euros, and I took the opportunity to do a general service as well.
