The main thing: as a screwdriver, this device is so-so, it is possible and it can be very useful, but only limited use in repair and construction work. The starting speed is too high and the force depends too much on pressing the button (i. E. , on speed, at a minimum and no effort, it can’t turn everything. In other words, the speed is adjusted as simpler, and not as correct for a professional tool it would be), therefore, in one fell swoop to drive a large group of screws into a material that cannot be destroyed by exceeding speed or accidentally over-tightening, it is possible to cope with the rest with a hand ratchet. In general, to assemble furniture from I. or, even worse, from other manufacturers, it is better to use a cheap, but profiled tool. I bought it because I got tired of constantly carrying my main DeW . t screwdriver on an airplane, and even without a shock unit. I specially took such a device, a Deshman one, but already from the "blue" series, so that with a small load it would work for a long time and more or less predictably, and then it could be repaired at least a couple of times. Or sell, Bosch all the same. It was possible to buy cheaper, but these are not the amounts that, having saved once, then get surprises with strange design nuances and a lack of spare parts.
