Am passionate about the Sally Hansen Insta Dri top coat, dries really super fast - not in seconds - but after 10 minutes everything is rock solid. The shelf life can I find also very good - one week the Mani hällt as by already. And another advantage for "Stamping fans" - Smeared the Stamping Design not - if I get this done, then you also :-) From me full credit, I will order again and I can recommend.
