I have used two of their colors already and I love them, they are different and not too neon as some other brands but they don't stick as well on my graying parts and they don't last as long as some other brands. I do love the ability to change the colors often though (which I do) so for me this brand is excellent because I get bored easily. You MUST use cool water when you wash your hair though or the color will definitely come out in only a couple of shampoos.
Great color!! Lasts really well, especially if you use some heat, washing every couple days, and rinse with a 50/50 Apple Cider Vinegar and water. It was very vibrant for over a month. I have purchased 3 and plan to use it regularly. I love it!! Also, very quick shipping and delivery! Highly recommend, extremely satisfied!
