After watching Manny Malholtra take a puck in the eye, I wear safety goggles all the time.
The Dremel was excellent carving out the new marquee on my arcade cabinet. It took a little while to get the hang of it. I find it very useful for smaller jobs, where I don't want to bother getting out a larger, better tool.
My kit has a gazillion attachments. I do not know what half of them do. It's great that they color coded the sandpaper/grinding attachments, but it would have been even better if the book wasn't in black and white. It will take me a while to sort out which attachments are most useful for what purpose. In the meantime, I think I found an attachment for writing forum posts, but it isn't working very well. Maybe it's not compatible with my monitor? All I get is a lot of scratches and smoke.
