Have had use for a couple of weeks and works well. However, the face of the hammer is falling apart and will likely break in another month or so. Not a bad hammer for the price.
I only use this demolition hammer occasionally so I don't want to pay four times as much to replace my Mac. Even shipping my broken hammer east would have cost more than this new hammer. Hammer feels like good quality. Should last me a long time.
I bought 3 of these hammers for a medium sized landscaping job I was working on. This hammer opened almost instantly, and each hit threw out some sand. The quality didn't convince me. There are better options, and if you're going to make a landscape, get a bigger one.
