I have a Revlon Colourstay Gel envy Polish in shade 300; All In.
I *love* this shade - it's one of those ones that looks a different colour from every angle; everything from a dark teal to a pinky purple to a blue, all with a bit of shimmer. Therefore, even if it was terrible, I'd still wear it.
The Gel Formula has a lovely finish to it. It goes on smoothly and evenly, assisted by the solid brush. It's a good brush, by the way! Nothing worse than spindly little brushes when you're trying to apply whole-nail polish and this is a good, wide, solid version.
The polish sets reasonably well ( I always top coat it though, which helps) but it isn't the speediest, so be warned if you're someone who can't sit still for ages.
The finish is gorgeously glossy, with that 'gel' look - a little wet, and shiny. Unfortunately, on me, it does still chip. Admittedly I use my hands a LOT between work, netball, home, the gym etc but I was hoping this range would be a magic cure all for that and it isn't. It lasts *okay*, don't get me wrong, but seeing as the bottle claims that it is longwear I did expect better... especially for the price.
All the Revlon colorstay products last the limit except for the nail polish. They haven't made it bullet proof yet!! I bought the 300 all in a midnight blue shimmer colour it's great for parties or evenings out, or summer festivals!! I usually wear nude pink or white but wanted to try something different. It lasted the evening but didn't survive the day. dark blue chipped nails is not a good look! Couldn't be repaired. I have yet to find a nail polish that doesn't chip after a day. It does last a bit longer then most
