I have and still us a Harbor Freight rotary, it's awesome and works great and I can get the same results with the Harbor Freight buffer as I get with my Makita 9227. The Makita is quieter, WAY better built and I haven't burned up my Makita on boats like I did the Harbor freight buffer, but still that harbor freight buffer for the price works great.
That $20 B&D unit from Walmart is a toy and most paints of any hardness will not only kill that machine, but it would take forever to do any type of correction. Then again, it wasn't built for serious detailing or paint correction.
When correcting with the Harbor freight rotary, I still prefer to finish out with a R/O polisher to avoid holograms, since it's very difficult for most people to finish out with a rotary hologram free no matter what type of polish or pad combo they are using. Most people that finish off with a rotary "think" they have finished hologram free, usually that's not the case though.
Anyhow, I haven't used either of my rotaries in months because I can correct way faster, safer and get much better results with a cheap R/O Griot's polisher, go figure. Technology and innovation at it's best.
