Review (1/5): Did not work with either of our UV lights to fully cure
First impression was the colors were not on the bottles, you have to do it yourself, really?
Then she pained this on her nails and we used a 50W UV light for 60s then 120s after that, and a second UV light after that as they were still tacky after this. Later they were not as tacky but still not fully cured hard. They peeled off the following day. Maybe if you have the entire nail salon setup these would be ok but not for the home user.
