Any CPFers use the multi mode switch on the Ranier or Pyranees?

Just wondering since these have been available for a little while, if anyone has any real world use with them and how well do they work and just a general review of the switch in how it feels if it is sturdy and how smoothly the transition from different modes. Also if there is any flickering between modes.

The multi switch works only on the Pyrenees & K2, not the Rainier
