I got this as a present from my sis and first I wasn't entirely convinced, but after using it for several times I really started to adore it.
It is the equivalent to the OPI Drip Dry Drops, which are gorgeous as well - just in spray form.
What you do is spraying this over your painted nails and it helps them to dry faster. It smells a little bit like artifical cherries and does its job perfectly. It works as well as the drops, but less messy. :-)
