The first impression was OK, but you can tell the same that you can not use this device for daily use. After the first time a small crack at the joining of the parts has already emerged in the second using a piece abgebrochen.Ich has got it off glued with superglue again and with much caution it can per se and unscrew again. Bad product from Bosch! My old part (No name) was better processed and kept 7 years. Not recommendable, almost looks like a cheap toy from China. This time, I am disappointed by BOSCH.
