Review (4/5): Had an issue, solved
My wife is a manicure specialist and tried a batch of different nail gels. This one is terrible quality. Even with using lamp longer it doesn't last more than 2-3 days. I wish I can return it.
Update 08/09/2019
Seller was able to refund me full amount and I found that an issue was potentially in my UV lamp. I will update review once will try to use it with another lamp.
