This demo hammer is way cheaper then renting one if you use it more then a day, or rent it on a Fri and bring it back Mon. If you need one for 4 or more days , it's cheaper to buy this and throw it away then to rent. Used it 4 days so far, a few hours a day, being over one hundred degrees in the sun. Works great and I'm holding it up on an angle a lot. Down flat would be a piece of cake. I'm removing huge concrete footings from steel pipes that made a fence. Not fun. But, this machine gives me the ability to take my time and not get heat stroke. Just a smart choice to make over a rental.
