Love this top coat, it's the best. Although... I feel like I've said that about Seche Vite... but this one is easy to buy in New Zealand so it's even better than Seche Vite!
It's got quite a thick texture which spreads really easily on the nail and is almost self-leveling so you don't need to worry about brush marks in the top coat.
The brush itself is wide with a rounded end so you can do the whole nail in 2-3 strokes.
The top coat gives a really shiny hard finish just like gel nails, although of course it doesn't last as long as a real gel manicure. I find it lasts a good 4-5 days if I'm careful but as soon as my nails start chipping or if I pick at them I take them off anyway. Any longer than that and I get bored with the colour too.
This comes off easily too when it's time to remove, and that alone makes it much better than a real gel manicure in my eyes. I want to be able to change my nails up regularly without damaging the surface of them or being stuck with the same colour for too long. So Gel Setter gives me the look of gels without the commitment!
