Updated after wearing for 1.5 months:
I own a LOT of nail polish.. a lot, and this nail polish is FANTASTIC.  Like any polish, you need a good bottom and top coat.  I use “Pro-FX Complete 3” for a top coat (big round bottle you can buy at Walmart).  I’ve worn every shade, but the orangey-coral color (I don’t think it’s cute.  The charcoal is on my nails right now).  I’m shocked that I haven’t needed more than 2 coats for completely opaque (with the exception of the pearl).  You do need longer wait times in between each coat, but I think it’s worth it.  I’ve gotten compliments on this every time I’ve worn it.  To be honest, I have worn from this collection every week since Christmas, when I received t.  With the bottom and top coat I use, the polish still has not chipped in 1.5 weeks, which is the longest I wear polish.  I switch each week, so I can’t speak for longer.<br /><br />FYI:  I ordered the neon shades, and there’s a pretty big difference in the formula.  The neon doesn’t go on smoothly, and it takes many, many coats to appear opaque.  I’m also not impressed with the lack of brightness.  I’m not sure if I just expected more from the word “neon”.  I won’t be purchasing the neons again, but I WILL purchase this metallic collection again.  TWO THUMBS UP !
