The chain saw is fine. She cuts up very well, even big enough so surprisingly silent electric diamètres.Moteur As seen in other reviews, the weight is not particularly light, particularly because of the significant weight of the battery. The main negative point in my opinion is the battery life: Between 15 and 25 minutes to cut the 40V battery, charging takes 2 hours. When we do a lot of cutting forces to space ca periods of cutting 20 minutes every 2 hours ... Not always super convenient. The alternative is to have either a 2nd battery or a bigger battery model but it starts to get expensive ....
