Today I just picked up my Harbor Freight rotary, and my first impressions on it is that whoever built it, didn't go all the way to make sure it was a quality fit-and-finish tool. The screws to get the handle on were virtually impossible to tighten up as the screw holes were too small, and I needed to use an extension to get it to work. I also noticed it isn't very well balanced with being very front heavy, and can be a bit noisy and make some strange sounds, like the PC. On the handle, you can hold it just fine, however on the trigger handle, I found that the trigger lock button was badly placed. The trigger is a direct on/off switch, and RPMs must be adjusted by the dial, which fortuneatly is blaced right where your thumb is, which does make that part easy to work with. I still would of liked to see the RPMs be adjusted through the trigger though.
Now, as far as the good parts are concerned, it defiantly is made out of heavy duty materials, and there is a certain heft to it, while still being a relatively light machine. This I did like, and after running the motor on/off and on high RPMs, I can honestly say that I don't see it breaking down any time soon. Overall, I would have to say for $25, this thing is a steal, and for that price, a great tool for someone like me to learn to use a rotary on. Sure, it does have its annoyances, but honestly I find it less annoying than the PC. Next weekend, if all goes well and I get my toys in the mail, then I will be buffing out the car, and if not, then the weekend to follow.
