I don't understand why there are so many good reviews. The device is from a well-known and very good manufacturer, but stupid. killed the first (new 300r.) bit for 30 screws, after tightening 56 screws (4 floorboards) he heated up to such a state that he needed to give a smoke break in 20-30 minutes or work in leggings. The conclusion is: 1) this screwdriver is for lazy people (5 minutes of work - 50 screws and 30 minutes of rest). 2) Need a decent supply of bits to work (if you can call it work) 3) no flashlight In the photo, the self-tapping screws that I twisted with them, the old rechargeable Bosch drives them five times faster and 3 times more fun!
