You didn't like the Opi ones? I haven't seen those but I would expect them to make good ones. The ends of the JB ones always fray and it seemed that the adhesive messed up the surface of my nails. I'm not sure that's what did it but it was when I started using them. The ones made of polish don't have adhesive. Some of them are cheaper than the JB ones, too. I like the selection of the JB ones slightly better but all of them are too goofy on the whole. I like to have some really subtle ones. I am not good at viewing my nails as separate from my outfit and they too expensive (all of them) to change very much. Oh, and the polish ones are quicker to do. I have mostly used Sally Hansen and most of them are meant to be used with the topcoat that requires a UV light. They get messed up with wear and the JB ones continue to fray, so in short, I just don't wear any of them as I would like to.
