I was very very excited to buy my daughter some of the super pretty colors they offered, and thankfully i followed my gut and i didnt buy more then i needed. i tested them out before i did her nails. and though the bottle says i only need 45 second to cure the polish after 7 goes under the light, testing between lights after the 2nd light round the nails where still sticky and tacky and still as i wrote this 2 hours after application and multiple mins under the light there is not change what so ever. this product was a huge let down and i will not purchase again
