Does anybody have these on there truck.... I am thinking about getting them but, I don't want to ruin my windows or window motors. I used to have the ones taped onto the paint, but hated that they were taped on. I would think that the in-channel ones would pinch the window when it gets to the top...

 

Had them one time and didn't have any problems with rolling up the window. They looked really nice tucked in but they didn't stick out far enough so when it rained the water actually dripped inside more than when I had the stick on kind.
Also if you ever go to the carwash and they have the driers that blow up and down along the sides of the vehicle, they can blow them right off if the blowers are strong enough. Had that happen once, so I could only use the washers w/ the driers that were above the vehicle.

 

I had the VentVisor in-channel type and was satisfied...by and large. A piece of the in-channel part broke early on and I finally got tired of pushing it back up into the channel. I bought the WeatherTech in-channel to replace them and I like these much better.

 

I've had the Weathertechs on my Avalanche for about 5 years now with zero issues.

 

I had the VentVisor in-channel ones for a few years and was very happy with them, didn't have any problems with the power window operation or window run warpage. Water still seemed to work it's way under them though, when it was raining and I was cruising, water would stick to visor and spritz in the rear corners...
