Review on Chicago Pneumatic CP870 Action Sander: Powerful Sanding Solution for Precision Performance by Rick Rogers

We use this at a commercial sign shop in place of a $275 unit with a very similar design. For sanding aluminum sheets and canopy frames - works great. Let's see how long it lasts, but if it lasts a year then it will be a lot cheaper to buy this device than a similar "industrial brand" that costs a lot more. The same grinding wheels are used. People who use it are picky - and they're impressed. I didn't tell them the price! :-) UPDATE 12/08/2018. Not only did it last, the guys at the store liked it so much we bought three more. Cheap price for value.
