Here is what we have figured out on cordless power tools... We use the rigid brand by Home Depot because they guarantee those products for a couple years. We just take the burned out batteries and chargers and stuff back to the store every year and they replace with new ones.

All the batteries and impacts and chargers and such are interchangeable which is nice!

Also each guy needs 2 drills and 4 batteries per day to keep everything cool (regardless of the brand). We are indeed very hard on tools and can tell you the best brands and deals for every type of hand power tool, various saws, etc...

Funny y'all mention that!
