A Mixed Bag, But Good Overall

I've found that the quality really depends on which shade or type of polish you choose.

I have a number of the creme colours and they are very good. Bold, pigmented, and last a decent amount of time. Good coverage in 2 coats (you might even get away with one coat for some colours, but I prefer 2 to get the full depth of colour).

I bought a metallic/pearlescent colour, which looks gorgeous in the bottle. It's so thin that you need 4-5+ coats to get any decent coverage on long nails. It's so disappointing because the colour is beautiful.

Thankfully, these are inexpensive, so I don't mind trying a few shades. I don't think I will be buying any of the metallic ones again though.

Like their colours!

I bought sinful colours because I really like their colours. One problem with this nail polish is that it takes a longer time to try and also does not last for a longer period. I will still buy it because they are like only $2-$3 CAD per bottle!

I have several shades of the Sinful Colors nail polish, in both the original formula as well as the two step gel polish system. The product typically requires two coats to be fully opaque, which is not a deal breaker for me as many of my pricier polishes require the same. There are a wide variety of shades to choose from and with such a low price point you can afford to purchase several.

I'M really enjoying all the colour choices . The price just encourages me to buy more each time I see them. 2 coats cover well and with a top coat there is not much chipping.

These polishes amazing.. they are very impressive for the price. But just depending on the color texture you do need to put on more than two coats of nail polish. Some others, like their glitter nail polishes show up great on just one coat alone.
I have been buying different colors in LA Colors that match my other polishes I have since I always seeing myself picking up a bottle of this whatever I go (L.A. Colors is available every where I' m at LOL), I do put a base coat on, two coats of LA Colors and any other polish that looks good together plus a top coat. This combination is amazing. No more chipping!! I could leave this stuff on all week. I will keep looking for more L.A. Colors Color Craze Nail Polishes, but for a dollar why not...
