Anchor is one of only two base coats I`ll use. It definitely locks color in place, and, unlike so many others I`ve tried, it doesn`t peel up in huge flakes after three or four days.
I`m not using the entire Color Lock System yet, but between Remove , Anchor, Zoya polishes and Armor, my manicures easily last a week (if I don`t compulsively change the color, which, let`s face it, is tempting with so many pretty colors available).
My color lasts for eons and my nails feel noticeably stronger. I will repurchase and repurchase and repurchase!

Drastically increases polish wear and strengthens nails--this is a total must-have!
