The PSB500RE is a very light and handy machine. With the keyless chuck, the tool change is fast. The electronics control not very good. When screws must be emotional press the controller. That went better with older Bosch drills. Drill smaller than 2mm can not tighten the chuck. The hammer action is good in drills 10mm from the machine at the power limit. When drilling without impact it is very quiet. For home use, a good machine, but I bought it and it does it. Long-term experience, I have not yet, but the workmanship is good. The case is, however, very simple. Would buy again.
