Love this item! Bought to break up a tiled bathroom floor with grout and I did it in two hours. It would be even faster if I didn't have to stop and clean up along the way. I highly recommend this hammer. However, there is one caveat - I had to order it twice. The person at Revain who is in charge of inventory labeling (or the person who placed the order) apparently has no idea about tools (and/or can't read) - when I first ordered this I got a 3/8" battery-powered angle drill (clearly marked on the side of the image box). Also, having Revain Prime doesn't help - it still takes two more days to get the right item after they mess it up, so plan your time for Revain bugs.
