It works, I had to cut a opening for a patio door through old thick brick.It works ......but. the blade spins clock wise which is not normal and if it grips its snatching back towards your legs....not good feeling. Also heavy, so if your cutting above your hip ect you wil get a work out. But for flat work, you can't do better for the money. Blade that came with it will cost you $100 .
