    Why, why, why?

    The only ridge filler that actually works! Everything else I have tried since this product became unavailable is terrible. My nails crack and split down the middle without this. OPI, please tell us why you stopped selling it. I would have given 5 stars if I could still buy it.

    Cracking

    Great product my nails have ridges and they split and crack beyond the nail bed at times and this product corrects all my nail issues so sad I can’t find any nail ridge filler or a product that works as good as OPI

    I’ve used this ridge filler base polish on my nails, and find it’s the only product that not only smooths the surface for the overcoat color polish, but also makes it last longer. I love it, and hope OPI continues to provide it for consumers!

    Destroyed my nails and recovery taking two months

    I used this product twice but it has made my nails very weak. They are flaking horizontally and vertically and hence I’m unable to grow them at all. I hope the damage will grow out soon but I strongly advise against using this product.

    A base coat, top coat and nail strengthener in one bottle, what's not to love? Product goes on smoothly, dries quickly.

    Bring Back the Product That Works!

    Haven’t been able to find anywhere. Actually “Out of stock?” (if so, why is your head of supply chain not replaced?) or is this corporate doublespeak for “We’ve discontinued the only product that delivers what its name says?” (in which case you need to fire whomever that ‘decision maker’ was who made that decision, because he/she is obviously making ridiculous moves, perhaps to justify their job?) Poor management in either scenario. Time to place your customer first, folks.

    Where is this Incredible ridge filler?

    Please, please bring this product back! It truly works wonders on my nails!! It's amazing and if your site says Out of Stock, I'm hoping it's not actually discontinued. Maybe issue is acquiring an ingredient... back on shelves soon...?

    Not for clear-only wear

    I've tried this as a clear polish option hoping the base coat + top coat would make it easy, but with two coats it starts to peel off after several days. Otherwise it looks great, and maybe it is a good option if you do color in between the coats. Opi's base coat plus the top coat sold individually are actually much better as a clear-only option, staying on for many days without chips or peeling.

    YES!

    A little spendy but worth it. I’ve bought cheaper & they don’t work as well. Decided to start doing my own pedicures to save money. This 1st coat / top coat made it look just like a professional did it. Really nice shine. Day 4 & no chipping.

    Perfect!

    I tried many clear coats in my life and this is my favorite for many reasons. I have thin nails and this really helps keep them strong. It does not chip, lasts a long time, comes off easy, and has a nice shine.
