My favorite thing about OPI is the names. They have the most clever names. About the actual polish: the formula is generally always great - almost always opaque in 2 coats, almost always buttery smooth application, wide color selection in the permanent collection and each new collection is right on trend with the colors. They have lead the way with interesting textures and special effects (The Mariah Carey Collection featuring 4 shades of "liquid sand" polish releases January 2013). I prefer the ProWide brush of OPI over other brands. This means the brush is wide and flat so it covers more of the nail with each swipe of the brush. Overall wonderful brand.

Love this nail polish! Not only is it completely genius to have 'collections' and 'special edition' colors...it's just awesome seeing so many collaborations. I'm deeply in love with the Muppets Line and the Nicki Minaj collection not to mention the brand new Skyfall collections...my fave now is my very first fratwurst :)

to me OPI is the most used and best nail polish brand in the entire world my mother and sister are both stylist and do nails as well and it is the only product the use

Best nail polish i've tried & i've tried A LOT!! Even better than 'Butter' polish which is twice the money! Love that you can find these on clearance too! My polish typically lasts 7-10 days.

I only use OPI. It lasts forever and I love the cute color names. One of my favorite colors is "Wooden shoe like to know" and their new euro color collection "Hands off my kielbasa".

Just love OPI. It lasts better than any other nail polish I have tried. A bit expensive but definitely worth the money.

After many years going to the salon and getting pedi's and mani's, I decided to purchase my own kits and doing them myself. OPI nail polishes is my go to polish for my nails. I think I have every color.

love this polish. my favorite. goes on so easily and always have such adorable colors

opi is very good nail polish

I love OPI they are consistently one of my favorite nail polish lines. They always come out with great new colors for every season and they last forever. I still have some of my first bottles of OPI and they still work just great. This is the best polish for a french manicure!

This is my all time favorite brand of nails polish. I have over 600 bottles of OPI polishes..... Yes, that many lol I love the colors and the names!!!

OPI Nail Lacquer is my favorite! It lasts longer than any other nail polish I have ever tried. I love the color range and really love the limited editions they come out with. And the tiny bottles are perfect for me since I can't wear nail polish at work. So its just a fun thing to do for special occasions. Highly recommend

I've been doing my nails (not a salon, ME), since I was a kid. I'm middle-aged now, and after trying all sorts of brands, from the cheap to the high-end pricey ones, I've concluded that OPI is the best.

I Love OPI! Great colors, fast drying with a glossy finish.

I just got two colors form the Brasil collection: Kiss Me I'm Brazilian and Live. Love. Carnaval. I also got La Paz-itively Hot-matte. I really love these polishes. Application is smooth. They last for a little over a week with a base and top coat. No streaks left behind. The brush is thick and wide that covers good surface area of nail. However it is not awkwardly huge. Dry at a reasonable speed. Odor of the polish is not strong as other polishes. Definitely recommend especially if value quality over quantity.
