Got the sample and went outside in the sun/heat of Florida and compared the NuanceRT to Transitions and Xtractive. The Nuance RT got darker and faster than Transitions in a more pleasing color which was just as dark or darker than Xrtactive! It also got light much faster than either Trans or Xtra. I need in trivex but "I believe this is the best photochromic I have ever tested!

I have been told it is very advantageous when used in the cold since it changes back at-least 2x faster than transitions.
