Very good cutting, I tightened the chain only once, no matter how much I pushed it. With cutting logs even 15 cm, it performed excellently.
Positives: Cutting performance, Starts easily, No vibrations, Good quality.
The only negative I found is in the position of the start safety as it made it difficult for me to grip. Its weight with the battery is around 3 Kg, it gets a bit tiring.

I work with the 5.2 Ah and I can cut logs with a diameter of 15 cm. If this continues without problems, I will be very satisfied. It also has a large oil reservoir, which is a great advantage.

powerful tool, the only drawback is that it does not have automatic chain lubrication. you need to add a little oil every 5 minutes

It doesn't have such a convenient handle. The most serious disadvantage is that you have to manually lubricate the chain.

I bought it for 90€ and used it for 3 consecutive days in olive harvesting. Excellent cutting of trunks up to 15 centimeters in diameter. The battery lasts almost all day with intensive use, both on trees and on the ground. I tightened the chain only once on the first day and didn't need to do it again. The engine didn't stop working no matter how much I pushed it.

The only negative thing I found is the position of the start safety, as it was difficult for me to handle it.
