I am a die hard fan of OPI nail polishes, and this product sounds like a must to make them last longer! I previously used the individual OPI base and top coats, and found that the base coat was good but the top coat took forever to dry! I mean like 1 hour of not touching anything unless you want smudges or streaks. It also required lots of careful brushing in order to avoid bubbles forming in the surface (very strange, I know). The effect was still good but is very labour intensive and time consuming.
I will most difintely be investing in one of these multi-taskers soon! OPI in my opinion is the only nail polish that lasts more than 3 days on my hands! At a push I can even make it last a whole week! It really is worth the money.
