Review (5/5): Works Fast!
I used gel polish WITHOUT a foundation base coat (I did have a top coat) and that stuffed allowed me to peel my gel polish off in just about 3 to 5 minutes! I used it on polish WITH a foundation base coat and it took way longer, about as long as acetone would. Again this was with gel polish, not gel nail builder/sculpter/overlay. Also, scuffing up the top layer coat of polish DOES make all the difference and allows it to work fast. Also, I can see why they don't want people to get it on their skin: it has a slight tightening sensation. Not painful for me personally or anything like that - just a feeling that something is on there.
