I've used the top and base coat already and I think they're fantastic- definitely worth the investment. I felt like I got a more polished overall look.
I only applied the coral blush tint yesterday so can't vouch for it's staying power yet (I wore 'Impeachment' last week and it lasted 6 days without chipping - so I am expecting the same from this).
I found this shade a bit streaky when applied - definitely needed 2 coats, maybe 3. Full disclaimer however - I'm pretty terrible at applying nail polish anyway so it could just be me.
Gorgeous baby pink colour, it was just what I wanted. Was a bit worried how it would go with my yellow undertone skin but I think it looks great. Very happy so far.
