Review (5/5): This ACTUALLY works but there are some things to note:
I'm shocked that this thing actually works. You put on a coat of mascara, wait for it to dry, then apply the heated curler to lashes. It doesn't look like it would work, but it does. The only bummer is that the batteries last for about a nano-second. After reading the reviews, I followed the suggestion to only have the battery in the curler when the curler is actually on. I don't leave the curler on long, just to preserve the battery. The first battery died after a few uses. The second battery seems to be doing a little better, but I've only been using it for a few weeks and I don't use it every day - maybe 4 days a week. So stock extra batteries, take them out between uses, and don't leave the curler on for long and you should have a killer experience with this thing (hence, the five-star review)!
