Rated 5 out of 5 by from Great product I have used this product for years and will not be without it. I use it weekly and it really works. I helps my natural nails and I have noticed a great deal of difference between this product on my nails versus others.

Rated 5 out of 5 by from Nothing Else Works I've used the prostrong product line for years with fabulous results. I've tried other nail products from QVC and they all went back because none of them delivered on their promise. Some even made my nails worse. When my nails went thin and started chipping after 40 I gave this a try and many years later will not be without the polish, fluoride treatment and nail files.

Rated 1 out of 5 by from Very Disappointed I have bought this in the past and was very happy with it. The one I just bought was thick, clumpy, sticky and wouldn't go on smoothly. I don't know whether I got a bad batch or not but I wouldn't expect it from a brand new sealed bottle. Going back.

Rated 5 out of 5 by from glad the Q is still carrying this product I get some peeling on a few of my nails and this product is the only one I have found to protect the nail from further peeling. Also has a nice shine to it.

Rated 4 out of 5 by from LOE Pro-Strong Great product; wish the thinner (extender) for this product was available online. Gets a little thick over time.

Rated 2 out of 5 by from Doesn't work After reading the reviews and trying a few other brands, I decided to take the plunge and purchase it. Well, been using it a month and my nails are still soft and brittle. The product also peels easily from your nails. Maybe it works on others that do not work with their hands or do alot of housecleaning?? Who knows. Definitely disappointed in this product. Going back to my Nailtiques. Works the best...
