In addition to the main tool and the various accessories, the set even comes with a stand and a flex shaft, which are extremely helpful for making precise cuts, grinds, and other things. Both of our sets have yet to show any real damage, aside from normal wear and tear (aka dropping them. Oops.)
Unless something strange happens, I would have to rate this above an actual Dremel in terms of usefulness and reliability. I'll post again in a few months whether this tool holds up. In the meantime, though, it remains a great bargain.
