This Review Title is LOVE! I got this for my daughter's 4th birthday and the content is: LOVE!  I got this for my daughter's 4th birthday, but who am I kidding, I got it for me!  First I did 1 coat of each color just to try it out.  It definitely needs 2-3 coats.  The 1 coat didn't last very long, so I've been doing 1-2 coats of clear also.  It DOES work when clear polish is over it.  I can see a change in every color.  Usually my feet are the cold color, and my fingers are the hot color.  LOVE this stuff!!!!!.There are other information for this review, one is This reviewer did purchase it and the other is 1 people think this review is helpful.
