Years ago I purchased a 9.6v Panasonic on the recommendation of a cabinet
shop that had five different makes of cordless drills. Loved it, but when
the batteries died after about 10 to 12 years it was replaced by a 12v
DeWalt, which I still have. Never have liked the DeWalt so purchased a
Panasonic 12v a couple of years ago and love it. Pick one up and feel the
balance compared to the other makes. I think the batteries are superior to
other makes also.

Just my two cents.
