Love this machine! Paid little to nothing when you compare to the big name brands. I was just about to buy Makita for 1200 (sale) when my apprentice showed me this machine. 1) it’s very light for a jackhammer, but heavy enough to get the job done without exhaustion. Honestly! I thought its weight was gonna be a problem, because jackhammers that I used in the past weighed at least 70lbs. 2) Accuracy was pretty much on point because my apprentice had little to none issues with the weight and control (and he probably weighs a buck 35, lol). So far we’ve plumbed 4 basements with it with little to no issues. The only thing I don’t like about it is, it can be a bit challenging to install or remove the bit. It gets stuck from time to time…don’t care too much for that but the price that I paid for it…trust me I’ll definitely deal with it.
