spend the money and buy once

: Don't know about B&D ROS, but own one of their drill before. It last two
: trials. The first time was OK but loud and vibrated alot. Second time the
: motor burnt out drilling a small 1/4 inch hole in DF. The drill had
: life-time warranty. I called them up. they told me to drive 20 miles out
: of town and fill in a whole bunch of papers and of course the receipt. I
: have to drop off the drill and come back a week later to pick up another
: one. The first 20 miles driving is good enough for me. Needless to say, I
: walked out of their door and disposed the burnt drill into their dumpster.
: No more B&D for me.
