I am not sure why so many people like this product. It peeled off my nails almost immediately. Also, my nails broke more often than ever. I am not sure if this was coincidence or if the product actually weakened my nails.

I am on my second bottle of this nail strengthener treatment. My nails had always split, peeled, cracked, etc. I found this and started religiously using it and I now have nice, longer nails! Works great!

OPI products are difficult if not impossible to beat. This doesn't make your nails super strong, but does add a sense of protection to your polished nails and a very nice shine when worn alone, which is my personal preference.

I have use this nail streighner for 3 years and it works amazing, my nails actually get harder when I apply this OPI and the amazing thing is that it dries fast unlike other nail strenghters. Definally will recommend this.

I swear by this product: use it on every manicure, every pedicure: EVERY TIME. I do my own mani pedis weekly and this helps to not only strengthen but also to create a barrier of protection between the nail and a color. I have never had staining issues when using this.

I have very thin, bendable nails, and I've tried numerous products available in pharmacy, nothing worked. Since this product has such high rating here, I decided to give it a try. Within only one week, I can tell there's a difference by pressing down on my nail bed. The first two weeks my nails remained the same length, but after that they started to grow longer faster. This stuff is amazing!

My nails break and tear very easily. In fact, it seems like I never have 10 long nails because at least one is broken. Using this strengthener let me grow them all out for the first time. I did need to add a new coat of polish every few days, but it was quick and simple. For "strengthening", I give this product 5 stars.

I lowered the stars because of the finish. I bought this version as well as the "matte" finish. I would actually recommend the matte version, because it has a more natural finish. This version left my nails looking like plastic. The matte version looks more natural--it blends in even though it is still smooth. I much prefer it, so I have stopped using this version.

If you plan to use nail polish after using this product, you should be fine. If not, I'd recommend buying the "matte" version instead: OPI Nail Matte 0 5 Fluid Ounce

I highly recommend this product. I first discovered this product when I had my acrylic nails removed; the nail tech applied it when removal was completed. I use it as a base coat & a top coat; the polish rarely chips so my manicure lasts a really long time, and my nails have never been stronger or longer. I will buy this product as long as OPI continues to sell it, and will complain it they stop!!
