I use to own countless of cheap nail polishes, but as soon as I purchased my first OPI (it was Nein! Nein! Nein! Ok Fine! if you were curious) I was instantly hooked and passed on the cheaper polishes to my sisters and mum.
I find that with a good base coat and top coat, that the polishes last a good week. I have barely any chipping issues myself. The colours are highly pigmented and to ensure a good, flat colour surface I do two coats.
I find that OPI polishes (or at least the ones that I have tried) do not streak like other polishes. The brushes are nice and wide which makes for an excellent and easy application.
There is a fantastic range of colour, so plenty to choose from! There is a colour for everyone from someone who enjoys the darker tones like Nein! Nein! Nein! Ok Fine! and Warm Me Up to lighter and brighter shades such as Dating A Royal and glitters such as Golden Eye.
I would definitely recommend this to everyone who is in the market for a quality polish.
The colors are great, but the smell is so strong it sometimes gives me headaches. It chips super fast and the bottles don't last long before going thick and gluey, before the happens the formula and brush are easy to apply with but it takes very long to dry.
Tips: Buy the smaller bottles if you want you moneys worth.
