Very thin, cracked first week.
I have only had these installed in my car a week when I put up the window on the drivers side and it caught on the corner and cracked the vent. When I looked at the passenger side, it also was cracking. We have always used weather tech with no problems, but unfortunately they do not make these for my Sorento. I tried to call on Saturday for a return, but no luck so far getting through. Will try again tomorrow.
