I have the old, and I have tried the new, Optimum line of polishes. They are great for beginners, as it takes forever to break-down the polish. But, for someone who gets paid, I desire a faster polish break-down. Hopefully when I get my
Menzerna my wish will come true. Also please keep in mind that some, but not all Edge 2000 pad users have had pad skipping issues with SIP. I heard a great majority of the Menzerna line dusts like crazy, while with the Optimum line, I have NEVER had dusting issues, which is a big plus. Good luck!
