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 had not 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 months i would definitely recommend dnd base and top coat for most clientsi am a licensed instructor and nail tech i have been doing nails for almost years i do gel polish by leaving the base coat on basically by doing a fill every 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 clients 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 is not 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 lotthat is the base coat only and on just a few clients i have not had any issue like that with the top coat i have since re purchased this duo several times i will continue to do so
