Fastrak Flex or Fastrak CAV?

Hmm. I don’t think so. They are both sticky, equally I thought.

I have a FasTrak Flex transponder -- it fits snugly in the leftmost corner of the dashboard, no adhesive/mounting needing, and bills fine

I leave my fasttrak flex on my center console in front of the cup holders. Works fine, perhaps due to Tesla's glass roof.
