Great little rock crusher. I ordered this for my cousin who lives out of state for 5-10 years. I threw him over the fence a few months ago. He told me he would be home for Christmas this year so I'm sure it will work as he hasn't asked for another one. He says he works great on concrete but had to use hacksaws to cut rebar. But otherwise it's a great tool. (The previous statement was meant as a joke, there is no truth in the statements other than that it works well for breaking rocks.)
