Hi,
I use opi in my salon in spain, and i love the products, i find some thing expensive but they are defo worth it.
The only thing i would say is don't get roped into using their cuticle pusher and nippers, i'm sure they're great but they cost a fortune and are not really any different from a basic pair. Opi used to go on at me to buy them and i just refused, they've given up now!
Feel free to pm me if you want any more info,
