The excavator couldn't get through the rocks for footings so I knew I had a few solid days of jackhammering ahead of me. Instead of renting, I decided to buy this and am sure happy that I did as it has already paid for itself. I started with the shovel blade, slowly chipping away at the boulders. After 30 minutes of slow progress with the shovel blade, I switched to the pointed chisel and annihilated whatever glacial till was in front of me in seconds.
The extra brushes arrived crushed, but a note to the Vevor support site resulted in a very quick response that a new set is on its way.
Very satisfied with this purchase.
