I bought this hammer to help demolish a 70 year old concrete stoop that was covered up by a deck. It had pulled some of the brick away from the foundation and needed to be demo'd by hand instead of with a skid steer to make sure the house didn't also get wrecked. I borrowed an Echo diamond saw from a friend which allowed me to cut the tough old concrete into 6-8" long pillars. With the hammer and spike attachment, I worked as big of a chunk as I could off at a time in order to make cleanup easier.
Working sideways under a deck with a 40 pound plus tool was tough and sweaty. The hammer DOES get hot with use, so it's best to work in spurts and then let it cool off. Also did I mention it is very difficult/hard work. The front handle is the best place to push into the target to reduce vibration into your body, however, it's more accurate to hold by the main shaft. Vibration damping gloves might help, but I didn't use them because it was so damn hot and I was switching back and forth from saw to hammer. The spike bit has lasted well. The skinny chisel bit I started with and it got dull before long. The wide chisel I barely used to try to get mortar off the brick wall. For this job, it was an indispensable tool. I think a good value, especially since I got it on sale. The cord seems a bit undersized for the current it's drawing. But it didn't cause a problem for me.
