Hammer/Drill switch did not function out of box. Two speed switch did not function out of box. I did not know how to give Zero stars but that is what this product deserves. There is NO excuse for this kind of shoddy quality/workmanship. I also recently purchased a Bosch (Dremel) rotary tool that failed after two minutes of use. Returned for repair and it once again failed in less than two minutes. I threw it in the trash. I should have learned my lesson about Bosch quality then. Be assured I will never order another Bosch product!!
