The drill has been very small and handy for their performance. Nevertheless, it has a surprisingly high performance by Constant Electronic. The speed selection and the Autolock function very well. Particularly when used in a drill speed selection is convenient because the wheel is mounted on the top of the machine and not the switch! The criticized in the other review "eggs" of the drill chuck is on closer inspection an optical illusion, because the chuck is not smooth, but has peaks and valleys. In addition, it comes from the company Röhm which manufactures high-quality forage. This also criticized noise at low speed I could tell though, but I doubt that there is a stock, as it disappears under load and higher speed. I'm not worry about it! To not engage the reversing switch following may be said: the direction of rotation is changed by switching the coals no longer by a switch and is functioning normally. I think Bosch is a very good model which succeeded in small, not too heavy, easy to handle and is still strong. I almost forgot it: the trunk is spacious, can be having to remove the device without the handle stowed in it, and it also offers plenty of space for more accessories! Definitely recommended !!
