I had them on a GMC Sierra and have them on a Tundra I'm driving now. I really like them. Allows you to leave window open an inch without possibility on rain coming in.
Will probably get a set from GM for side windows.
I saw a similar deflector for the sunroof and was wondering if anybody had experiance with them.
They work great if you install them yourself make sure you have them lined up before they touch the car once they stick they are hard to remove and if you remove them they wont stick very good. Also dont touch the tape the oils on fingers will make the tape not stick.
