i got a Craftman 19.2 volts set for christmas one year. drill, recip saw, circular saw, light.
the circular saw, is a joke. about only thing it is good for is small size lumber, with a limited amount of cuts.
the recip saw, you get a little more life out of battery, it is ok for small jobs but that is about it.
drill is good
light, it is ok, but have switched over the LED lights. the light is better used for camping, or in a crawl space or like to light up a given area.
=============
to be honest, i will take old corded stuff over cordless any day. granted you need to mess with cords, but the couple extra pounds of less weight, smaller size design, and more power you get from corded stuff, just pays for itself.
granted battery operated stuff has there use, and i limit battery operated tasks, to odd ball little projects, or tossing in my vehicle, just in case a project needs something were there is no power.
it is one of them. if you do not have the right tool, you get yourself in a bind type of things for me. a battery stuff regardless, have there nitch.
