Really good product. Demolished the slab for an old house with it (200sqm) and didn’t miss a beat. Only downside was the oil it came with had been squashed by the demolition hammer on the box when it arrived so there was oil all over the hammer that needed cleaning out maybe something to look at for packaging. But overall great!

Excellent value, works well more hits than some big brand named plus the choice of spade or pointed attachments
