This is my new favourite topcoat. I bought this after breaking my bottle of OPI Rapidry, and while I really enjoyed that I think I prefer this one just a bit. It is very quick drying, which I love, but doesn't cause any shrinkage. It also dries down to a high shine finish, a fact which I am happy about as I like a super glossy finish from my top coat. The shiny finish is gorgeous, and people often ask if my polish is Shellac or gel when I wear this, even though I am just wearing one coat of it over normal polish. It reacts well to all my polishes, I have no issues with shrinkage, slow drying time or chipping. I actually feel like this top coat does make my manis feel stronger, harder and more resilient to wear and tear. I usually get around 5 days wear from a mani when I use this top coat. This is a little pricey, but cheaper than OPI's version, so I will continue to use it and definitely repurchase. Good To Go is safely my holy grail top coat.
