True wireless electric saw, he needed one, here it is finally! The grip is excellent, including a good balance front / rear which prevents muscle fatigue. An automatic safety prohibits any accidental starting. In addition it is really light. It is a modern tool that can be criticized a little autonomy but personally, I always leave in charge when I do not use it, so always ready to serve. But precisely, the socket for connecting the charger is void, fragile and difficult to use, PS2 style between taking ordis and S / Video. We lose time looking for the meaning, one is afraid to bend the pins, it's a shame! How have engineers have invented such a thing. Or is it an idea for business to hope to sell some transformers? Too bad it was almost perfect.
