This is amazing stuff. I've gone through so many bottles of this, it makes your nails healthier and is SO SHINY and dries fast. Love it.

Good results from this product - strengthened my manicures by providing a base and top coat that dried on hard.

This stuff did make my nails sturdier and protect them pretty well - it worked better than any treatment formula I have ever used. It didn't really do anything to fortify the nails themselves, though, I would say it was just the fact that the lacquer itself is so thick that protected them from damage. Overall, good results, and I am keen to try the Advanced formula.

Only qualm was that it became very thick near the end of the bottle and I had only had it for a few months.

Made my nails weaker, now I'm scared to use it.

I used it alone and also as a base coat. My nails peeled and cracked SO much more.. I'm sad and disappointed, I was really hoping it would work.

I like it as a base coat, but I find that it reacts with some of my polishes as a top coat and turns part of them darker...

AMAZING! My nails were SO paper thin and damaged from previously having had acrylic tips on but this polish really did it exactly what is says; hardened my nails. I was able to bend the tips of my nails before they were so weak and now they are rock solid! Didn't expect this to work this good if at all when I bought it so I am pleasantly surprised!

I took this from my sister last year, and it was amazing! Recently though I ran out, and had to buy a new bottle. The packaging has changed, and I think that the formula has changed too - before it was nice and thick, now it seems to be thinner and doesn't dry as fast. Still has a nice gloss to it though, and I just apply 2 coats instead of 1.

I use it exclusively as a top coat on my fingers and toes, and it makes my toenail polish last for over a month without chipping! I only need to redo my toes when my nails grow out too much and it becomes unsightly.

On my fingers, I normally use it as a top coat to a french manicure, using Sally Hansen "Get Strong" Nail Strengthener as a base coat. It is too glossy and thick for me to use as a base coat, but it works well for a top coat. My only complaint is that it takes forever to dry, so make sure you let your base and colour coats dry completely before applying this! It's not so obvious over a french manicure, but over colour the smudges are more noticeable. I find that my nails last for 4-5 days without chipping, using it as a top coat.

Also worthy of note, as some reviews claim that it contains formaldehyde - the new bottle I bought clearly states "formaldehyde free" on the packaging.

My nails are brittle and break/peel frequently so I picked this up for $2.99 at a local grocery store. This product has definitely helped with the issues I have had and applies as a pretty thick clear coating. My nails feel stronger and have been growing at a faster pace than they normally would.

I love this as a basecoat! I apply a coat of this, 2 coats of color, then Essie Good to Go as a topcoat and my nails do not chip at all for at least 3 days (which is amazing since I have little kids and my manicures used to last a day or two at most). Even bright red polish stays put completely! Love this stuff!

Hated this. Ironically, my nails tended to break more in the shower when I have this on than when I leave my nails bare. Plus the edges of the dried polish always get caught in my hair, resulting in a bit of nail polish being ripped off. Once I even managed to peel off an entire layer of dried nail polish from my nail! Not recommended for flimsy, brittle nails as protection, or as a base coat/top coat. Did I mention that it chips like nobody's business?

I've been using this to seal in my nails after my manicure is on and I love it. The day after a fresh manicure I apply a layer, making sure to seal the edges and will repeat every other day or so. Since I've been doing this, my nails feel super strong and I haven't had any peelies whatsoever!Dirt cheap and love the brush.
