I really like the OPI Infinite Shine polish line. They system provides a great lasting mani - I change my nail polish several times a week, and I only reach for Infinite Shine polishes if I have a special event or need a lasting mani for a few days (even a week!). The primer and gloss also work with regular polishes. I highly recommend this gel-like system.
I really like the Sally Hansen Miracle Gel line. Great polishes, love the Sally Hansen wide brush with the flat stem - excellent polish distribution and makes for easy application. However, after a few uses, sometimes the staple comes loose on the brush stem and the bristles loosen or fall out. Good polishes, but you do take a risk with the brushes.
I love this matte coat. For the price, I did not have high hopes, but this is one of the best matte top coats I've ever used. I always seal in my mani with a quick-dry top coat first, then use the matte polish over it. Dries quickly and smooth, without dents.
