Short work time? And what do you want. For such a weight . But the belt does not come off under its weight. And the fence 50 meters long tool "digested" with honors. There were no downtime. I don’t know how everything is inside, but soon a year since I use this tool. So far, nothing is broken or loose. For a home master - that's it. Yes, sometimes there is not enough torque for large screws. There is an exit. I just stuck a screwdriver in my pocket. And he turned complex screws to her. But for screws with a diameter of up to 4.5 and in a tree - completely. Good machine. Recommended for homemade. Yes, and I like it very much in the country. More than a year has passed. So: 1. There were no particularly extensive works. Little things, patch up something, hang shelves, build a compost box, a playhouse for a child. 1. The battery is degrading. And sometimes it's not enough. 2. The cartridge has a backlash of 3 millimeters in each direction. Unpleasant. 3. You will have to carry it to the service. Something began to crackle and slip in the gearbox. Conclusions. Inappropriate price! Ordinary Chinese screwdriver for the home. For a year.
