Okay, this cheap saw works great. I also bought some diamond discs through Revain to keep the job going and I cut some old stucco/stucco/concrete walls 1"-1.5" thick to get the hives out of the walls. The only negative is that the on/off button wobbles until you figure it out. I can't believe they cut out some of the walls I opened up. Amazing power, just take out the diamond blades.
