The colors of Sinful polish are really good and really varied. I know I've gotten some that you only see in high-end brands. The lasting power, though, isn't as great as some others. But, I just use a good topcoat and base coat, and it seems to stay a few more days that way.
I am so surprised to say this, but I love this stuff! The smell is totally addicting, and as someone who hates lotion, I did not think I would enjoy or use this. But, after getting it in the Sunshine VoxBox, I keep it next to my shower and always spray afterwards. It doesn't feel greasy and the smell is light but lingers just enough all day. I will definitely repurchase when it's empty.
