I used this dye for almost a year and a half for my whole head and it delivers!
It does stain your surrondings and fingers if it gets in contact with them so be prepared with lots of towels and take your time.
I have always used Directions due to it being sold nearby, and when I first used "Flamingo Pink" it was incredibly (almost glow-in-the-dark) vibrant but I found faded alot quicker, using this, it washes out to the colour of the flamingo pink and lasts a LOT lot longer than it.
I love this colour, but be warned, now that Lily Allen has pink hair - its lost its cool! I changed to blue!!
