Review on TEMO DIAMOND CUTOFF: Enhance Your Dremel Experience with Compatibility and Precision by Jonathan Unruh

The wheels themselves aren't that bad, ONE of the kind I've been able to use. The spike contained in "1" is junk, useless. I bought it for a specific task, it barely worked (cut out the inside of a 2" piece of PVC) so don't worry if you're buying it for anything other than one time use. The arbor screw broke off on first use, allowing the wheel to spin freely on the arbor. And no, I didn't remove the screw, that's just junk. Terrible quality. BUY ELSEWHERE!
