All of my shellac polish nails "fell off" within 4 days. I'm not kidding. I spent $40 plus $8 tip thinking that the nails would last at least a week if not the 2 weeks they say. Yesterday I opened up a make up compact and I heard a snap... I looked at my nails and noticed my right thumb nail was clear and in the sink was the shellac! A full shellac nail in the sink. I've never had that happen. Slowly but surely today they've all come off - one came off when I was putting my hair in a pony tail! The products they use are extremely cheap. They said they'd fix them but to just put the same crap on? No thanks. They'll never get my business again -- expensive lesson.
