Of course, its main advantage is the absence of a wire, but it is inconvenient to work, either the shape of the handle is semi-pistol (I have no idea how to hold it at all), or something. Comparing with a wire sausage, which you hold as you like, it lies well in your hand in any position, somehow it is uncomfortable with this one. Probably a matter of habit. Again, this stupid battery shoe infuriates me. I chose riobi for the price-quality ratio, there are several of their tools, but everywhere this shoe gets in the way and in general the shape of the battery is stupid, shtosh, I endure. Well, it would still be nice to have a and a speed controller for that kind of money. Although if you compare other Akbshny angle grinders, also without a regulator, maybe the features of the technology, although cheap brands have an adjustment)) I also noticed that the switch, although convenient, but if you put it "on your back", then the switched on switch does not touch the ground, but should IMHO turn off. In terms of power, it is certainly a beast, and of course it eats the battery, if not in itself. Those. 2.5 Ah is enough to file a thread on the little things, to polish it. It is generally unlikely to work for her constantly, probably 9 Ah and it will be enough to work for half a day. Oh yes, despite the fact that the gearbox mount seems to hint that it can be rotated, I did not succeed by unscrewing 4 screws. Looks like you have to take it apart to turn it around. And I want to turn.
