Question: How long have you owned this Proxxon Belt Sander, and has it held up to use? Is it your "go to" tool, or what do you prefer instead? Thank you.
Document: This is a GREAT sander, about half the size and weight of a regular belt sander, but with plenty of power to get the job done. It sands flush on one side to get into the hard to reach places, and as it fits perfect in the palm of your hand it does not tire you. The action is very effective in sanding flat and even and changing belts just takes a few seconds. This is a great tool as are the other Proxxon tools I have bought.
The belts are small and so will wear faster due to the sheer lack of square footage so it's a good idea to have a belt cleaning block around to extend their life.I've yet to find fault with it apart from it's price, however, small always equals expensive if the quality is good and I can't complain about how well it's made. I have a bunch of Proxxon tools and for the most part  they are good quality, solidly made and precise.
i used this sander no more than two hours . i never even had to change a belt on it, before it burned up. very expensive chinese junk.
The sander works well enough when you get the belt on. It is hard to push that little lever on the side to change the belt. Yoy have better luck pushing in the front rollers.
I do quite a bit of mini scale stuff and this mini belt sander does just what a belt sander should do, only smaller. Though tiny, it's surprisingly solid and has ample power for it's belt size. Changing belts is simple, as another reviewer said, it's easy to just push the roller in. I recently tested it's abilities by grinding down some 4" disks of phenolic sheet. It was easy to control and powerful enough to sand it down without much difficulty.
Timely delivery,well made sander.I do light intricate sanding and this sander works very well.It has more power than my other sander ,does not fade out.With the open front it sands curves.
Answer: yes
