For this price, the best, given my fleet of Makita cordless tools and the presence of several 6 amp batteries. By the way, I ordered an 18-type amp from alishka, we'll see. 18 Ah with Ali in fact no more than 4 ampere hours. And on a chain saw, it's even less so. Pros below: Well, at least the price. And so I knew exactly what I wanted. Well, quick change is certainly fun, but it's a desirable option. Different cons: It is a pity that there is no quick change of equipment, which is in the reciprocating saw from OBI. Well, or at least it was worth putting the key in the kit. I am a blind horsefly, the key is fixed there on the carcass of the saw.
