I haven't, but those links are the ones that come up the most in a few of the online forums.
The problem with all of these dash covers (and having a light-colored plastic dashboard) is that they will discolor it because of the rubber/latex backing.
We're hoping to have one more rig after this one, so I also want to try to keep it in as decent shape as possible for resale.
I haven't found that I've needed any cover on the dash so far (with the cat). But, if our dash ever cracked or started looking badly, I would try one for sure. We put a big blanket on the dash for our kitty (which she LOVES). So far, so good!
