I've warrantied Batteries, no issues at all. Also a small flashlight failed, I guess they had issues with them, got brand new one, has worked great for several years. Just bought a new 1/2 inch Fuel M18 drill, I finally killed my old one or should say I wore out the forward reverse switch. Owes me nothing, outside in the rain and snow, can't tell how many 1 1/8 holes(3/4 conduit) it drilled in to steel J boxes, but probably over a thousand. Hammer drill was used a ton drilling 1/4inch anchors. The new one is smaller and more powerful. Haven't seen any of their US made hand tools yet but should be filling display racks at HD soon.
