I still have this one lying around somewhere at home... but I never use it anymore, for the simple fact that it didn't seem to work. At all.
I rarely paint my nails, despite a huge collection of nail polish (mostly OPI). And I always seem to chip my index fingers, within a day of painting them. When I first saw this product, I just HAD to have it.
When you apply it, it's very runny/watery, and it has a tiny wee brush (not the same size as a standard OPI applicator brush). I put one coat all over my nail; and it instantly soaks in and make my nail look chalky.
Following the instructions, follow with base coat, colour and top coat.
And the result? Still got chips in all the same places, within the same timeframe. Disappointed, to say the least!
I have a small sample bottle of this. Barely used as it's an extra step prior to base coat and not sure how much it works to extend nail polish wear. Didn't see much difference so easier to skip this step and rely on my top coat to prevent chipping
