Ossepostroitels of this type are very useful, without it in the decoration, as without hands. But for the money it could have been better, I guess. If I had to buy a new one, I would buy bosch again, despite the shortcomings. Different pros: laser precision. Build quality and relative strength: fell a couple of times - did not go astray, checked / adjusted by a plumb line. Cons: It was the third decade of the 21st century, BOSCH did not dare to organize in this device either a battery or mains power through a power supply. Eats a lot of batteries. 4 batteries - one working day.
