This is the best top coat I have ever tried!!1 I barely put 2 coats on my nails, and usually only 1 coat and if I use top coat,ever after 4-5 hours(and who has 4-5 hours to dry your nails completely?), my nails smudge, and next morning, they are never glossy. At then ultimately, I have to reapply the topcoat, and go through the whole thing again. With this top coat...I put it on at 10 pm at night, dried for 5 minutes...and I woke up to glossy, shiny nails! Really, for the first time in my life. Has already saved me much time and bother with reapplications. And only at the very most 5 minutes drying time! Thank you!!!
