To my surprise This machine was fantastic
It broke through high strength 6 inch Of cement with ease I don't believe any other manufacturer can come close to the price that was the most surprising thing $160. If you need to break cement up and you don't want to spend $1200 for a main brand.
I figured it was cheap enough for me to use it for one job and possibly throw it away if it was junk.. It turned out to be quite an impressive machine and it's hanging in my tool shop for the next cement job. If you need to do a cement job and break cement and you don't want to break the bank or your hand or back This is the machine for you strongly recommended
