Rated 4.4 out of 5 by 145 reviewers.
Rated 5.0 out of 5.0 by great sander This is a very effective RO sander. Good dust collection with the provided bag. Far less vibration than my P-C RO sander. The on/off switch is a bit fiddly, but that's a minor quibble. March 4, 2015
Rated 5.0 out of 5.0 by this orbital palm sander works exactly as one would wish the power switch is a little tricky to toggle though February 2, 2014
Rated 5.0 out of 5.0 by milwaukee ROS I just purchaced this after burning out my porter cable ROS. I love this sander fits nice in your hand, aggressive when needed, quieter than my old one , grabs the dust very well and the PS sand paper is nicer to work with than the old style hook and loop. very big bang for your buck recommend to all my friends as well as some foes lol December 6, 2008
Rated 5.0 out of 5.0 by Better than the rest The quality of this sander is evident as soon as you take it out of the box. The extra long cord makes it a pleasure to work with and the variable speed feature is nice for sanding hardwood / softwood. The only warranty that i know of that beats the 5 year milwaukee one is ridgid, and this is just a better sander January 6, 2009
Rated 5.0 out of 5.0 by Monster sander power This is actually the second time I've purchased this sander model. I bought it because I have a woodworking buddy and we both needed/wanted one. This sander is powerful and best of all the dust collector works. I even sand inside my shop now without getting sawdust every where. It's quiet and smooth running. Love it and do not hesitate to brag about it. November 12, 2013
Rated 5.0 out of 5.0 by Perfect finish sander This sander works excellent and fast. Takes cross grain marks out without a problem. Used it on all sorts of projects and I haven't used another sander that works near as well as this one. March 25, 2015
Rated 5.0 out of 5.0 by Wish I bought this years ago, quick change and variable speed I needed to sand all my kitchen cabinets and this sander is a god send. It is so easy to change discs and the variable speed is great for final sanding. Add everything together with Milwaukee tool durability and you get one great tool. March 21, 2013
Rated 5.0 out of 5.0 by Great product! Best I've seen. Sands great. No swirl marks. Speed settings are easy to use. Feels great in your hand and comfortably easy to control. August 21, 2013
