It could be a perfect accessory, but its body, which is made of relatively thin and soft plastic, cancels out all the effort. You assemble and adjust it, but its plastic parts cannot withstand the intensity of cutting even a small branch. They immediately loosen up and the controls become unstable.
Even if someone considers using it at a low speed, it is not possible because the chainsaw blades get stuck in the wood and it stops. At a moderate speed, it cuts for a few seconds and then the chain gets stuck.
Because the design is very good, I believe it would be perfect with a metal body.
The chain and the guide are good

Cheap and not very sturdy plastic, they require careful handling and proper assembly. With a rechargeable battery from the 2000s with 600-700 rotations, it did a decent job. With caution and patience, it can even cut thicker branches. I also used chain lubricant in the chain channel, although it wasn't necessary, I think it helped a lot. And yes, it requires two hands to operate and you'll need an extra one to hold the branch when needed.

Unacceptable product. Basic assembly instructions, where if you don't have any experience, you can't manage. Very poor construction quality and no power at all. It couldn't cut a 4cm branch and the handle came off. Money wasted.
