Almost everything is good. One of the small problems is that it collects a lot of debris and branches and gets stuck under the chain movement cover.
The batteries are 2 but disappointing in terms of duration and charging speed.
For gardening tasks and as an auxiliary tool, yes, but I do not recommend it for serious work with many trees. I regret the money, not for the quality but because for the time it lasts with the 2 batteries, I could have bought a Chinese one for half the price.....

It cuts much better than I expected! It hasn't gotten stuck anywhere so far, it has cut everything I have given it up to a diameter of 6.7 cm, usually in one go. Sometimes it has vibrations that definitely have to do with the way you hold it when cutting, but still nothing significant, just slightly annoying.
It's not really meant for cutting small things (e.g. as an alternative to pruning shears) because it pulls leaves and small branches and gets clogged. It opens easily for cleaning, of course, but you can't do that all the time.
The batteries are so-so, and I have the strong impression that one of them is "weak," which is why they give it as a gift. At least they have a light that shows how charged they are, something that a Black & Decker drill I have doesn't have and is a significant lack.

It is very good, cuts perfectly if you have experience, purely for pruning and both batteries last all day of professional pruning, used with both shears and larger chainsaws for thicker trunks, in short, it helps a lot, quickly and simply.

Just received and opened an olive. Great ease with the extension, it cuts well with few vibrations, not in all cuts but it has. Five stars at first sight impressed me, it replaces the hand saw perfectly. The extension is worth every penny...

Το πηρα πριν 10 μερες , δυνατο εργαλειο,,κοβει κορμο παχους 30cm για πλακα,,,η μπαταρια κραταει αρκετα

The chain was backwards and (obviously) not cutting. I turned it around and everything is fine.
It does not have automatic lubrication, you need to have oil.
It easily gets clogged but cleans easily as well.
