Ive looked at the Klutch polisher closely because I was interested in it as well. I found it to be the basically the same polisher as the $29.99 unit sold by harbor freight. The HF model is lighter and has a nicer handle.
Unlike their air tools, I was not impressed with the Klutch polisher. Its a OK polisher, but compared to the HF model and price, it is sub-par.
I used a $300 makita polisher for years, and when it finally broke I bought the HF polisher. Ive been using it for almost a year now and it has been great. I highly recommend it to anyone. And defiantly recommend it over the Klutch.
