Review on Matte Black Low Profile Ventvisor/Rain Guard For 2014-2018 Silverado & Sierra 1500 Crew, 2015-2019 Silverado & Sierra 2500HD-3500HD | Auto Ventshade [AVS] 774033 4Pc by Keith Leach

If I could, I would give it ZERO stars for the product. Even after I had the problem with the driver window deflector on my '15 Chevy, I purchased another set for my new GMC. Same problem with the driver door but easy to fix now. However, I just took off my 2nd rear right door deflector cause it warped so much it interferes with the closing of the window. The first one took at least a few months to warp, this one did it in a few weeks.It came slightly warped but got worse over time. They appear to not be able to get the rear window deflectors correct. Yes, they replace, them, but I"m tired of installing them.So, I am ordering a set of EGR deflectors.Attached photo shows how it is warped compared to an even surface. The deflector in the picture is less than three weeks old.First, the driver side deflector would not allow the window to close. The drive's side window has the auto close feature, and will stop and open if it contacts something as a safety feature. Well the feature works great! When the window hits the deflector at the top it opens. So, I took the piece off and filed down the front inside edge a bit with a Dremmel and it works.I had to remove the old tape and install with new 3M tape. After a few days in the heat, the center dropped down. and I had to remove the deflector. Could have been the taped I used; however, now the back windows are doing the same and they were installed with the tape that came on the deflectors.I believe the problem with the adhering to the window seal is due to the company's great idea to cut costs and safe plastic and tape by not have a continuous area of plastic and tape to contact the windows seal. (Saves on plastic and tape costs and spread over thousands of deflectors it can safe quite a bit of money.)The same AVS deflectors on my 2013 Silverado had a continue plastic strip with continuous tape and never had a problem and actually lived in a hotter climate (southern UT). Or they are using cheap tape; not sure.I have ordered some 3M super type tape to install and use. I'll give it a try, but if it does NOT work, I will just junk the items and NEVER order another AVS product again. And I am considering an AVS front bug shield, but will wait and shop around.
