Revlon's Top Speed line of nail polishes are fantastic for around $2. I own at least 5 of these in various shades and they are all fantastic. My absolute favorite color (I've already gone through 3 bottles) is Lily, which is this beautiful blue-toned lavender. Cloud is super close to Lily, but more blue, almost periwinkle with a hint of lavender. For this particular color and most others, one coat is enough for the color to be opaque. Sheer cotton (it should be obvious by the name, but for some reason my scumbag brain was out of order at the time) is sheer though I expected it to appear opaque as it is in the bottle, but it's still great as a french manicure base color and also does build up into an opaque color with 2 or 3 more coats. The silver color, Metallic, is ridiculously amazing. It looks like poured liquid silver!! For the cream and metallic colors, I don't find a top coat necessary, but sometimes the pearl colors may appear a little streaky without top coat or I'll still put on a top coat if I want the polish to last longer. With all these great things said, there is one huge con: just as the polish dries quickly on your nails, it also dries quickly in the bottle. It gets pretty thick and goopy by the time you get toward the bottom of the bottle and the brush doesn't reach the bottom (seriously?), you'll need to tilt the bottle to get to the polish. But for the price, it's not going to kill your wallet to buy a new one. I highly recommend these!
