Actually I picked up a set of OPI`s RapiDry set from Winners, containing their RapiDry Spray as well as the top coat.
I had high expectations from this top coat, being OPI and all. A fast drying top coat is a must for me. I mean, once you start using them, you can pretty much never go back to regular polish application. You just can't.
Overall, this top coat did not make me happy. I would recommend Sally Hansen Insta Dri, it`s much cheaper and performs better, even tho it's not my absolute favourite.
While I'm at it, I'll tell you what I thought about the RapiDry spray. It's my first non polish quick drying product and it worked okay. I spritzed on nails about 60 seconds after application and it did help my nails dry a bit faster than on their own, however, I don't like the delivery of the product: the spray. It goes everywhere! I still need a topcoat as this spray will not help nails be as glossy and shiny but I do use this for quick manis or when I need to layer coats and I am short on time.
