Let me say for the record that these are amazing.

The colours are really opaque , so if you're trying to hide something on your nails, these are my number 1 choice, not that I have anything to cover, but...

Anyways, They glide on really smoothly and they can last a while. But what I hate about it is that it chips every so often if you're not careful. On the other hand, the bottle lasts forever because you pretty much only need one layer each time, except for "Suzy Says Feng Shui" in their HongKong Collection. I found that one is to be kind of streaky-ish. So, I had to maybe use 2-3 coats. But overall, I love their formula, even though there is a price to pay for it.

The formula isn't too thick or thin. In fact, it's like Goldilocks and the 3 Bears. "It's just right." So, I recommend you try it out at Sephora or something, because you know, they let you try out ALL their colours.

PS: OPI has a sister nail brand called ChinaGlaze. I don't know if you've ever heard of it, but it's probably like OPI, except a lot cheaper. I've never tried it..yet, but I'm pretty sure they'd be almost the same quality, if not a fraction less. Just to let you know.

O.P.I nail polishes are great! I've been wearing them for a few years now and they are among my favorite. I love the variety of colors they offer, which sometimes are unique to any other brand and they last quite a long time before chipping. The size of the brush is pretty big, making it easy to apply the polish in just 3 strokes. They are not streaky and the formula is very smooth. I haven't had problems with the nail polish becoming too thick either. My favorite colors are Heart Throb (a delicate sheer pink), You Don't know Jacques (a grey taupe), and Big Apple Red (a classic bright red).
The only negative point is that they are a little pricey (almost $10 a bottle) and this may steer people towards cheaper drugstore brands.

Even though OPI is little bit more expensive then your department store brands, the few dollars are truly worth it. OPI comes in many colors and you don't have to apply many coats to get the effect you want. Not only are there many many awesome colors to choose from, OPI lasts a long time. So if you are someone who doesn't like to change nail polish on a daily or even a weekly basis, I recommend you spending a little bit more $ for it. ULta is a great place to buy OPI for a little cheaper than you would anywhere else. They also get smaller sets of it for really good prices just in case you want to mix and match it up with other colors in the set.

I too was introduced to O.P.I. polishes in a nail salon. There are so many beautiful colors to choose from, it would take me forever to decide which one I wanted to use. They also have very unique names so they are easy to remember if you want use it again. The polish is great, goes on smooth and always shines. It stays on longer than most so its really worth the cost.
The price may be a bit more but so worth it. You actually save in the long run. The array of colors and the staying power is wonderfull.

I own a few OPI nail lacquers. Personally, I am not very fond of them. After applying it and letting it completely dry, I find them chipped after only a few hours of wear.

The rainbow selection of colours - there is something here for everyone. They go on so well and look fantastic! Definitely a high quality lacquer. If you want a little splurge, this is it.

I just wish they weren't so much money in comparison to the drug store brands (which at times, can be pricey in my opinion). If you can, find sales whenever possible to make it really worth it.

Great range of colours... good quality, lasts long, long wear... everything you can ask for in a nail polish! A must!!!

Long lasting polish, goes on smooth. Great colors!

i love love LOVE these polishes. the colours go with virtually any skin tone, and the polish itself is long lasting. its great to give as a gift, but even better to receive ! a definite must have !

Got these as a gift and I must say they really do leave my nails shiny..normally I am more concerned with chipping but OPI is long lasting and chip resistant.
