I have thin nails, prone to peeling, and traditional polishes never last on me. I had gels for years, even got all the stuff to do my own, but those wrecked my fragile nails even more. I tried other no-light polishes, with mixed results. I actually liked Wet n Wild’s way better than the Sally Hansen 2-step, which always chopped on me. The CND weekly polishes are a holy grail item for me and I actually threw out all my other nail polishes. I now have 4 colors and the top coat. They all go on smooth, and the brush is perfect. You do need to agitate the bottle a lot of keep the consistency right, and some of the colors drag a bit if you try to apply the top coat too soon, but overall I’ve yet to find anything better. I buy a new nail polish every week or so. My nails still peel and chip on their own, so nothing looks perfect on me for a week, but as fast as these dry and as easy as they are to remove, I have no problem swapping out my nail color every 4-5 days. Cannot recommend enough.
