I loved the Norvell One but have recently switched to Norvell Venetian One which was sent to me by mistake. Both are express solutions that adjust to clients skin tone and rinse in 1-3 hours. It is funny because my experience with the regular Venetian was less then stellar.
I did a quick review of solutions that I have tried on my youtube channel here is the link:

The one I would most like to try is Black Magic but to be honest I have a hard time using and recommending a
solution that has to stay on for 8-16 hours. Even for me I like to rinse and forget about it.
Also I sometimes feel a bit limited by what local distributors carry in Canada and have been surprised by exorbitant customs and duties on imports. :(
