When they say it dries in 60 seconds, it's no joke - it really does dry that quickly.
I find the brush makes it super easy for applying polish, it's probably one of the better brushes I've tried on a polish - the wider brush makes it easier to apply polish on your nail in less coats and the curve on the tip makes it good to get close to the cuticle. I'm not a big fan of the bottle size, I honestly wish they did these in a bigger size! It does take a few coats for the colour to be completely opaque. Even though it says 60 seconds drying time and it is true, I would still give your nails an hour to fully set so they don't chip in the next few days.
The only downside for me was that the bottle itself dried out quite quickly, I'm not too sure if this was because of the bottle size but I found that the polish did get quite thick after about a month.
I love these nail polishes. the apply streak free and dry within the 60 seconds they say. the colour pay off is nice and the colour is true to the bottle, i own 3 of these in orange/peach, lilac and turquoise. They are affordable and you get a good amount for the price. I paid $5 for each :)
