I have owned almost exclusively Bosch power tools (presently green line, but I seem to remember they were another colour back then) for at least 40 years.
I have noticed a remarkable decrease in quality in the last ten years or so, so much so that I will probably no longer buy from them. The last ones were a circular saw (PKS 55A) which has the motor and blade badly misaligned with the base (cannot be fixed), and a PSB 650 RE portable drill with an almost useless electronic speed control, especially at low revs, and a keyless chuck which is plain junk. Both bought about three or four years ago.
I now came to regard Bosch power tools of the green line as another case of Stanley and the Handyman - amateurs deserve no more than junk, so why not give them plain junk? So much better if they can be enticed into buying it... Until the day...
