This is the best nail product I have ever used! I do nail art, and this will dry 4-5 layers of nail polish in 2 min. to the touch, and 20 min. all the way down. Keep in mind I use thick polish layers. It also helps to prevent chipped tips. I may have to touch them up after a week on the tips, then add a fresh layer of top coat. I have had my polish jobs last up to 2 weeks depending on the brand names I use. GREAT STUFF!!!!!!!!
