This thing is a little jewel. I decided to try this one and a electric demo hammer. I had a tile job lined up that I wasn't quite sure how it was gonna come up. I stumbled across this one somehow and glad I did. At first I didn't wanna trust a battery hammer at all, especially a name i don't know. But for the price of this i thought it was worth trying. Needless to say I'm gonna be returning the electric demo hammer I ordered at the same time. Simply because I didn't have a reason to need it since this thing nailed it. I did put a thinner edge on the chisel bit it was dull and blunt. Unlike some other reviews my battery only came with 2 bars so I just threw it on the charger immediately. I like the weight of it, I like the variable speed trigger (remind me of variable speed but not sure if this is). The battery seems like it'll last and I didn't run mine empty yet. It popped it all right up and in a bucket it went out the door. For the price and the beauty of not needing 110V this thing is a jewel.
