Seems like a really cheap alternative, but it works wonders good self contain little unit

The first time I used it the clear glass in the front that shows how much gas is in the tank cracked and started dripping gas on it still trying to fix the cracks filled it with silicon and a small piece of rubber hoping it will hold other than that it did a great job

Put threadlock on every bolt! The bolts vibrate loose, often within 10 minutes, even after they've been reinstalled. Also, the power may not be enough for heavy applications as I've found that the chisel won't always move even at full power. The jackhammer does start easily and it is not difficult to manuever.

Followed the instructions, lubricated, added fuel and engine will not start. Tried to start it for over an hour. Requesting refund.

I’ve built a lot of fence over the years so I was skeptical, but after using it today I’ll tell you this is the best purchase I’m made in years. It fired right up and did the job of busting up concrete. In two hours I drove 44 7 foot t-posts in heavy clay and rock.
