Love this tool May 30, 2011
Reviewer: Jeff from Surprise, AZ United States  
So after using this tool, I found that this was the best thing ever. It was simple setup plugged it in and turned the water on and this baby simply worked.   I had my countertop ground down and polished in two hours, I'm so happy.

Powerfull March 18, 2009
Reviewer: Pietro Oscala from Newport  
The M100K I purchased created the perfectprofile on my counters. I purchase a 1 1/2" bulnose wheel and I was very happy with the result. The profile wheel I bout from rotoblat fit right on the m100 and I was able to profile the entire counter top with no effort and the fool proof guide made it simple. I received my FedEx email right away and new that the package was on route, that is always a good sign of a good company. I like your product and will be happy tom come back and get more stuff, I was able to purchase a core bit and profile wheel over the phone with you guys but it was not listed on your sight you might want to put this on there because it is a must when doing counter work for faucet install. Thanks again toodaloo -P.

Didn't loose my manhood with this unit! January 22, 2009
Reviewer: Alexandro from New Mexico  
I am doing some concrete counter tops and I got to the stage where I need to polish the surface. I was using the Cheng line of products and in the instructional Video it recommends using a wet polisher in th 0-4000 RPM range. We'll I though I could get away with using my own grinder, needless to say at 10,000 RPM pads were flying. Wasn't worth loosing my manhood over a counter top. The company I bought my concrete coloring had a cheng unit but wanted $400 for the variable speed unit...forget that I can hire someone to do it for less than that. I found the rotoblast unit on line had the rpms I needed and sure enough the pads stay where they are supposed to-on the unit. I found the unit very easy to use considering I have never polished with a wet unit before. Not much too it just attach the skirt and hose and start going through the grits. I would recommend this product to anyone doing counters, it worked for me and I don't really consider myself that handy. A+ for customer satisfaction when it comes to product and delivery. Received my tracking number within 24 hours as promised and the unit came 4 days later.

Reviewer: Stephan from Dallas  
Needed the unit for a job urgently, the factory managed to ship it to me overnight and get it here on Saturday so I could finish my job. They even called on Saturday to ensure it got here. Just wanted to thank you for customer service unlike any other!! Great product A+
