Customer Reviews — [1] Rating: 5 Date: 2008-02-08 Summary: A workhorse! ... I'm surprised to read that some of the other reviewers were less than thrilled with this sander. I love it! This is my second one, and I specifically hunted down this model. The fit in my hand is perfect. The first one lasted about 9 years of heavy daily use. I always said I would be thrilled if everything I bought was of the quality of this little guy. ...more
[2] Rating: 5 Date: 2006-08-17 Summary: Hard worker at a inexpensive price ... I am a handyman/contractor. I own several of these units, and basically I find them "just fine". First off, they are inexpensive enough that I don't fear loaning or losing them on the job. They perform radically better than the Mikata orbital sanders I bought 5 years ago (to be fair, new Makitas probably do better too). Now I wish I hadn't waited so long to replace my older units! Yes they are noisy ... but in my opinion so are all the other units on the market. I wouldn't use ANY palm sander for more than a minute ...more

Customer Reviews — [1] Rating: 4 Date: 2008-08-14 Summary: Good sander, few flaws ... When I had decided to become a woodworking hobbyist, I spent about 6+ months doing nothing but review tools. My goal was simple: find quality tools that I could learn with, make decent furniture with, would last me at least a couple years while I learned, and most importantly would not break the bank. I am still learning, I don't have a couple years under my (or my tools) belt yet, and I have build a few projects (mostly shop items.) Although it has only been a few things I have built, I have used all the tools I purchased. ...more
[2] Rating: 5 Date: 2008-06-07 Summary: superior dust control ... Only sander that actually has great dust control that doesn't cost hundreds of dollars. Just keep the pleated filter clean with your air compressor and dump the dust after every project. The only better sander would be the festool ones with powered vac to match but I can't justify that for my shop. THIS IS A GREAT ALTERNATIVE. ...more
Editorial Reviews — ... Amazon.com | What sets this sander apart from the ever-growing pack of random orbitals is Bosch’s new Microfilter dust filtration system, which the maker says will trap particles 60 times smaller than a human hair. Eight dust ports on the pad surface extract the material up into the filter, keeping it out of your lungs. The sander itself, a palm model, is relatively lightweight and comfortable in hand, thanks to the ergonomic soft grip, yet the 2.2 amp motor will power rotations from 7,000 to 12,000 RPM with...more
