Weathertech Wind Deflectors

I was debating on trying other brands and/or the tape-on types but deciding to give weathertech another try despite the price and a some bad experiences with them on two other cars I had them on. This would be my fifth set and would be my worst experience. Installation was not difficult but these had clips when my previous sets did not. These ales did not have adhesive for the rear pieces. Definitely a lot of resistance rolling up window near top. Both rear pieces bowed out, and both also cracked first time rolling window up slowly. Looks like too much material was left where the visor goes into rear channel, likely to increase tension to keep them up. I filed down broken ends, reinstalled, and now there is barely any bow and it looks cleaner. I heard some noise when rolling up the front windows so hope those did not crack as well. I will be trying another brand for my daughters car.
