We've been dying to try it, so we finally broke down and bought one.
It's basically a dremel, but has a plastic guard cap to hold the nail in place. Love it!!! Well Meena & Heidi don't REALLY love it, but they are going to learn to get used to it.
Wish it came with different emery heads. Perhaps a coarser one as well the current one. Maybe speed settings would be nice.
