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!

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.

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.

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

From a detailed report on chemicals in beauty products: "One product in particular, OPI natural nail strengthener, received the highest hazard rating of all 14,100 products in the database. The company’s nail polish and nail treatments contain toluene, formalde-hyde and dibutyl phthalate—three of the top ingredients of concern."

Of all things to avoid, this one seems to be the worst! Simply not worth it.

I used this according to the instruction and it seems to me that my nails became somewhat more brittle and prone to breaking.

Also it gave my nails an unattractive yellowish look.

The people who find this works seem to wear nail polish over it. Maybe this makes a difference but it is not mentioned in the product instructions. I don't typically wear nail polish.

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!
