I'm specifically writing about Pretty Polish.
First as the other posters commented on, the polish is REALLY streaky.
Second it is 10ml for $5.50 USD. I find that really expensive, because I used about 2-3 coats, and it seemed I used a LOT of product already. Doesn't feel like you can get many uses out of the bottle.
It is a very lovely non-shimmery colour, but for the price and the streakiness, it just isn't worth my time.
Though I used my ambassador code to get it...I think that I am better off using their makeup products instead.

This polish has cute packaging but is streaky even after 3 applications. Colors are limited.
