Found this demolition hammer as I was looking for something that will help me break out some concrete in the back yard. Initially I was skeptic that this will do the job and to my surprise it actually came through in everything. I was able to demolish all the concrete, which in some parts was about 24 inches thick. This was my first time using a demolition hammer and it is easy to handle and use. Really like how easy is to change the chisel. Great product!
