Sally Hansen Diamond Shine Instant Nail Hardener is rated 3.2 out of 5 by 20.
Rated 5 out of 5 by from Made it through an obstacle race! I have been using diamond strength on and off for months and it works so well for me! However, I never thought about writing a review for it until yesterday. For as long as I can remember my nails have naturally been flimsy and have peeled. After I started using this product all of that stopped. Furthermore, I participated in a very rigorous, intense obstacle race with this product on my nails and did not break a nail! Not even a chip! I was climbing up hills, ropes, had my hands in mud and everything and like I said not a chip! And my nails are just under a quarter of an inch long so there's definitely length there to break! The trick is to use it consistently. I make it a point to removed and reapply at least once a week. Great product!!

Rated 5 out of 5 by from Repeat Customer I love this product. My nails were just awful the last few years and I used to love them. I bought this bottle and I LOVE my nails again. They grow so fast and strong. I recommend anyone having issues with the nail polish peeling...clean your nail with nail polish remover before you apply the base coat. It removes oils and allows the polish to soak into the nail.

Rated 1 out of 5 by from Not Happy - Just Bubbles I had acrylic nails for years, and then 12 months ago decided to grow my nails naturally. I was surprised at how good they a have been. I had used other brands and was extremely happy with them, and then thought I would try Sally Hansen products because they have a great reputation. I purchased tghis hardener and wish I hadn't. Everytime I have used this polish - whether as a base or top coat it just bubbles. Every single time. So disappointed.
