I use it with a Dremel. I've had it for about a week. It is sturdy. Especially for wood carving, it does a very good job, even on hard wood. However, it also works well for removing paint from wood. It doesn't easily get stuck in the wood and go on an uncontrollable ride and end up on a finger. However, it's not as aggressive as the Kutzall in their Extreme Coarse version, which if you're not careful, they don't spare your fingers. It doesn't cause vibrations in the flexible shaft of the Dremel. It does its job very well.
