I was pleasantly surprised at how long they lasted, comparable to the much more expensive brands. Worth the wait, if you have to wait for them. by .. Jeffrey Smith () These discs are well constructed. The paper backing is the thickest that I have seen and they don't seem to wear out as fast as other discs. I had to wait a month to get them though.

Hurwitz (VT) I am a full-time, professional furniture maker, and over the past 20 years have tried all kinds of brands of sanding discs.
