Review (5/5): Awesome product!
Absolutely thrilled with this product. It works exactly as advertised, basically as a hybrid of hard gel and traditional liquid & powder acrylic, combining the best of each. The material from Gelish claimed "zero waste"-which I was, admittedly, skeptical about; the fact is though, is used correctly, there actually is zero waste. One unexpected benefit is adhesion: I've literally never seen a product adhere so well to natural nails.
I read in a couple of forums that it can't be layered with other products, such as gel or acrylic; however, I've found that I can do so without any problems.
I do usually find that I need to turn over my hand, after I remove the forms, and cure the underside of my nails for about 15 seconds (LED).
The only potential drawback I've found to this product is that it's not clear. It's sheer, which gives a final look very similar to that of a natural nail. If you need truly clear material, like glass, you're better off staying with hard gel.
One important note, though: this review is for the "sheer" poly gel. I recently thought I'd try the cover pink version, expecting it to be roughly the same as the sheer, and was utterly disappointed. It doesn't cure all the way through unless you apply it in very thin layers (which would defeat the point of using poly gel, so...) and even then cures so brittle and fragile that the nails will break if you look at them. My guess is that it has to do with opacity, which would mean the white is likely to act the same as cover pink (Fyi, I use a 48w hybrid LED/UV lamp).
