I've been using OPI for over ten years and they are fab, great colours (many with such depth and special finishes) but you do need to prepare your nails first to return them to the correct "PH" - i.e with "chip & skip" or "seche Prep". I have a few Leighton Denny, but they're not the same and I find don't last as long, even with a nail preperation first. One good thing about OPI too, is that they last and last. I still have a colour that I got 7 years ago and it has never seperated and is still as good to use! I do have a bit of an addiction to OPI though and have loads and loads...
