Well, over the past 25+ years I had a few,

Makita - 9.6v drill. Lasted about 4 years until it fell off a ladder and broke. No experiance with the newer ones.

Milwalkee - 18v combo kit. Loved the Sawzal, That was about it though. Drill smoked about three weeks after I got the kit. Turned ito such a pain to get it fixed, I went and got a Dewalt drill. Then the charger died.

Ryobi - Anything beyond light duty, complete junk. Although, I am happy with the miter saw. Smoked three drills and snapped the chuck off a fourth. The recip saw required more coodination to use than I had some days.

Dewalt - Just about the only cordless tools I own anymore. Very happy with them They just work. I have the 950DW drill which granted, could be used as an anchor for a aircraft carrier. But, 9 times out of 10, I don't have to break out the corded drill. I admit, they haven't been perfect, I did get the chuck to go free wheeling once. 35 minutes after I finally got it to the service center, it was fixed. I did go out and get a 20v compact drill as "back-up" Been happy with that one also.
