This works quite well in small spaces and in the sand. Contains 5 sandpaper corners. Once they run out you can only get replacements through the company and prices go over $100 for 5! Ridiculous! I found a whole box of these on ebay for $30 that should last for years!
for home repair. easy to use and gets into hard-to-reach places. Working with new tools requires training in this device. In addition, you can buy various triangular sandpapers that come with the sander. It seems that the brand of sandpaper sent tends to stick to the sandpaper. Makes me mad.
I bought this for cabinet sanding to get into some of the tighter spots my random orbital sander couldn't get through. The triangular design definitely fits in the corners but doesn't live up to my expectations. I still had to do the job by hand because it basically made a lot of noise and didn't sand the surface much.
