I am a nail polish junkie and I must say, OPI is by far my favourite nail polish brand! The consistency is nice (not too thin or too thick), and the colours are quite pigmented (depending on the colour itself). One of the things I like most about it is that they are also easy to apply and also dries quickly in a reasonable amount of time. It is also fairly easy to remove the nail polish (apart from their glitter polishes, which are just as hard to remove as any other glitter nail polish) and they don't usually stain your nails (but again, this is dependent on the colours, as some colours are more likely to cause slight staining than others). I always apply a base coat and a top coat, and I find that my OPI nail polishes usually last for about a week without chips. However, this will be different for everyone as it depends on what kind of jobs/activities you do that will affect your nails.
The only thing I don't like is how it is so hard to pick which colour to buy, and then to decide which colour I want to apply as well (since there are so many colours to choose from in their range). To be honest, that's about the only thing that I don't like about the OPI nail polish range, if that even counts at all! If you can save up for one, I would really recommend trying it. I did, and now I've never looked back! :)
I've had my nails done for years. New tips, back fills and pedicures and I always choose OPI Nail Lacquer - a different colour each time. The range of colours is wonderful and the quality is excellent. No chipping and very little fading.
With a top coat my nails last 3/4 weeks. Yes, I am sold on this product and always happy to recommend it. Pay a little more and get the best, its worth it.
