Well priced tool that works very effectively. On the heavy side but the result of that is that zero effort is required to get the blade breaking concrete. I only tried using the chisel blade, which did the job brilliantly. As a DIYer I am very happy with this purchase. For those who have previously commented that they didn't know which oil to use; it's clearly shown next to the filler cap. The hammer was exactly as described and did what it said on the tin.
