Hate Dewalt, big, heavy, shit batteries
Ridgid, heavy and awkward
Bosch, love'em batteries not so great
Makita, not a big fan in the past ... checked them out last week and they almost beat out a T15. I think Makita is back in the game
Ryobi, great cheap tool, they really last no matter how hard I beat them
Panasonic, great feel and ergos for me, not cheap though
Milwaukee and PC, just don't like'em anymore, feel cheap and crappy
Hope that helps Joe
