Let me say that this is a fab little product!
I normally have pretty weak nails and was really impressed with how strong my nails were with this product on...after doing the bend-y nail test of course. I used HTR with coloured nail polish as a base and top coat and was impressed that my nails lasted couple of days without chipping. Normally they wouldn't last past a day or night.
The polish on its own also adds a nice natural sheen to your nail if you wear alone. Definitely recommended!
I like this product. Initially I was mostly interested with the idea of covering yellowed nails which I sometimes get after wearing deep coloured polish. The purple tint did seem to help. I actually used it as a base coat (which it isn’t) and it sat well under other polish but when removing left more colour than a good base coat. Nails haven’t broken since using and look good. I’ll keep using this.
