This thing is a Hoss. I busted up a bunch of concrete, and for the price, I figured if it lasted the job, it would be well worth the money. The equipment is holding up great and this was a worthwhile investment. The weight is kind of heavy but it's a big jackhammer, it has good grip, the design seems functional. It is noisy but it's a jackhammer... I'm sure it's quieter than commercial grade equipment. The speed and acceleration works great in busting up relatively large areas of thick concrete. Worth the money. Would recommend
