I had the Tesla (weathertech) ones in my previous Model S, and now have the ones from Evannex in my new Y. The Weathertech ones were fine. They more like a stiff plastic. The came with a very strong velcro that made me not want to risk removing them (and I didn't) when I traded the care. They were fine.
The Evannex ones are softer, more rubbery. They reminded me of the padding that goes under carpets in your home at first. I first thought they were a little weird, but they have grown on me. I like the feel. The come with an adhesive backing. I haven't removed the backing for that yet, but will do that soon. I hope that helps in your decision.
