Review (2/5): Not a fan
This thing stalls out on my acrylic nails, and yet it actually burned me when I tried it on my natural toe nails (apparently, I wasn't moving it around enough, or maybe my toe nails are flimsy), so I really don't know what you're supposed to use it for. I'm not happy with it, but it's not the kind of thing you can really return once you've used it. I don't know, maybe you can, but I didn't try.
So it sits there, neatly and quietly charging til I figure out if it will work for my polymer clay stuff. It probably will, but since I bought it for nails and it won't work for that, I can't rate it very highly.
