I own a fashion blog and I test a LOT of nail polish every month. This is by far one of the best nail polishes I have ever used. It stayed on at least 2-3 days longer than ANY other polishes. I wore it for 7 days with barely any chips, touched it up with a thin coat on all nails and it lasted another 3 days. I can't say that about ANY other nail polish. The only thing that has stayed on my nails, chip free, longer than this were Sally's nail strips. I HIGHLY recommend this nail polish!!!!!!
