I received this top coat as a gift and would never have splurged the $20 that it costs. At first, I loved this top coat, it seemed to dry as the name suggests, in 45 seconds. However, I soon realized that this top coat gives me crazy shrinkage, and thus, causes my polish to chip around the cuticles where the top layers of polish have shrunk away. Additionally, being tinted pink, I have noticed that when wearing very light colours, this top coat will tint my base polish. Wearing this over white especially, seems to change the colour significantly. I do love the packaging and its speed, but absolutely cannot stand the shrinking. I would say this polish is just a 3 free, more expensive version of Seche Vite, and definitely do not recommend it for the price tag.
