I use my Dremel about 6-10 times a year. Yes, they may not be as good as Dremel brand sanding drums, but in my local gear, Dremel brands cost about 0.75 cents each, while this product costs 0.5 cents. The couple fell in love with a big project, but you can't beat the price. They come with 2 drum application tools for each size. I suspect either a Dremel or other tool would suffice, which I think is a great idea. There are enough drums to last me more than a lifetime and I can leave the rest to my boys.
