I really like it! I use shellac and gelish. I do mine at home. I just peel it off at the end of the week and do it over (not that it wouldn't last longer) but I mess with my nails constantly -- former nail biter that can't leave her nails alone for too long.
I works great for pedicures too, would no doubt last even longer. I just think it's such a pain to take off your toes. I would do it on my toes for like a cruise/vacation but not for everyday.
