Great stuff! [SEP] I bought this because of the positive reviews and it arrived quickly. (the product I usually get was out of stock) So I used this right away on myself and another nail tech tried it too, she loved it!  After about a week we hadn't run into any lifting issues with the base coat and the top coat was still nice and shiny. So I started using it on some clients and it has worked really well! Now after using it for a good 6 months I would definitely recommend DND base and top coat for most clients.<br /><br />I'm a licensed Instructor and nail tech, I've been doing nails for almost 20 years, I do gel polish by leaving the base coat on. (basically by doing a fill every 2 weeks, not a new set.) I only remove the gel polish color and prep the re-growth and apply base coat to the new growth. That said, the only issue Ive had on a couple clients is the base coat can get a little soft after several months if my client's hand are in water and/or chemicals a lot. So I need to  remove the entire base coat and start all over every few months. This isn't the end of the world but to avoid having to do this, I use a different base coat on clients who are hairdressers or for those who have their hands in water a lot.<br />That is the base coat only and on just a few clients. I haven't had any issue like that with the top coat. I have since re-purchased this duo several times. I will continue to do so. :0)
