If you want a cheap and affordable nail polish with many shades and colours, then you should try Sally Hansen nail polishes. I bought the bright pink and purple shade from the insta-dri series. I must say, they dry out VERY fast, so one down side to this was that it began to dry on the brush so I had to re-dip the brush back in the polish many times. Other than that, it dries very fast and it has a great brush to apply the polish with.

I don't know why this is called Insta-Dri, it takes just as long as other polishes I have, and usually I need two coats anyway. This polish is gummier than other polishes, even other Sally Hansen products.

Others really enjoy the sturdy brush but I feel it is clunkier, perhaps if you have trouble gripping smaller polishes but I find the brush too wide for my fingers.

I love the xTreme wear collection, it's quick dry, not gummy and shows great colour, I find there is no advantage to this line whatsoever.

This product is awesome. I am a so glad I bought it. My manicures last for two weeks with no chipping, using this product. Lots of colors to choose from.

Great colors and polish. The brush is a lot firmer than most and makes application very easy and consistent. Dries very quickly.

My favourite nail polish. :) The brush is nicer than most nail polish brushes I've tried. It helps you make it really neat so you won't need to clean up with a q-tip after!! And it also takes in a lot of nail polish so you only have to use one coat.

This polish is pretty blah! I mean, it's not bad, but it doesnt stand out eithe. Colours are ok, opaque, but still require 2 coats for even coverage; I did not find it to be extra resistant nor did I find it to dry quicker than your average polish. The color range is average as well, nothing special. I would most likely pick the Hard as Nails line over this one.
The only unique thing would have to be the brush, but even so, it might be to big and wide for some.

This nail polish is a must have in my nail polish collection. It comes in fun bright and trendy colours and really does what it says it does! It dries super fast, and I find I often only need one coat and I'm out the door. The only downside to this product is that it doesn't last. Even with two coats and a no-chip top coat it's still chipping away after only a couple of days. At least it dries in literally 60 seconds to reapplying it isn't time consuming at all. It's great if you find yourself with a last minute job interview, date, or special event.

Sally Hansen's Insta-Dri fast dry nail color has a perfectionist brush that contours to any nail, so color always glides on precisely, quickly, flawlessly. And, the exclusive Flexiglass Complex combines beautiful, brilliant shine and super strong wear. I’m using Racey Rouge right now and it glides on wonderfully. I’m not very good at painting my nail, but this brush seems to make it easier for me. The brush has a straight edge on the tip witch seems to make it easier to use and cover your nails more quickly. Although it says its Insta dry it sure wasn’t for me. It took my nails a good 40 minutes to dry and even then a few were still tacky. I made have applied to much because even though it says it covers in one coat, that will depend on how long your nails are. Over all Sally Hansen’s Insta-Dri fast dry nail color worked out well for me and I can’t wait to try more colors.

This is a great collection of nail polishes because it comes in tons of fun colours and is very affordable! It is best for when you quickly want to splash some colour on your tips and don't have time to wait for them to dry. Careful though, this collection is designed for speed not quality so don't be surprised if it starts to chip after 24 hours.

This product is great when you are doing you nail right before you are going out. but dont expect it to last for a long time. without the effort of putting on a top coat it will chip the day after. I have the black and the big bush allows a speedy application, and it has a solid colour so one coat is usually enough.
