I love this entire set. What to start with….durability! I am a factory worker, always using my hands. I run a brazer to basically weld parts together, so my nails get wet, dirty, you get it. This polish really does hold up! The lamp is one of the easiest and best, with all the light sensors, you really are getting FULL curing coverage. Need more colours!!! I will gladly buy them (but secretly so my husband doesn’t see,lol)
