I'm a huge OPI fan. That's pretty much the only nail polish I will buy (because I've become a huge nail-polish-snob like that. Ugh.) However, since seeing Essie's Turquoise & Caicos on several bloggers last summer (I know, I'm so behind the times), I decided to take the plunge one year later.
I've never used Essie polish before and while it cost the same as my OPI normally does per bottle ($10), apparently I completely overpaid because the links above are much cheaper. Le sigh.
Onto the review! I find the T&C isn't a super thick formula, so while I did my standard two coats, three might have given a solid coverage (but then that's five coats with base adn top coat - far too much work for me). The Mink Muffs on the other hand (errr foot?) covered nice and opaque-ly with two coats. Normally I'm not a fan of thin brushes, but I find the Essie polish to be a bit more liquidy than OPI and thus a think brush is fine as it covers easily since it spreads well. The lasting power isn't bad, certainly comparable to OPI. As far as the shades go, I like their collections but find OPI has a bit more dimension to their colours.
Verdict: I'd buy it again, but still reach for OPI first.
