This is an excellent product. I normally hate the smell of nail polish remover but this is very nice. The biggest thing is 'it works exactly as advertised'. The remover bottle is easy to activate just put your cotton ball in place and press down until you feel the moisture on the ball. Press onto the nail leave for the recommended time pull it off in the direction of the nail tip. I gently cleaned up a couple of places it didn't quite get all the polish and the nail was left clean with none of the usual 'white' residue. No nasty smell! I'm convinced & recommend it.
