Cordless drill/driver/impact for dummies!

Rigid only has that battery deal around xmas time I tried to get it in the summer and Home depot said the no longer offer it, that was about 5 years ago, I called rigid about it and they told me it was a one time deal so I bought Hitachi, then when my buddy had the problem he called corp office and they told him that it was for home use only not commercial and he through all his rigid tools in the trash and bought all Milwaukee, so if you have a free replacement battery deal tell them you only use them at home.
