Bests & Worsts Reviews from Amazon

Neat product, grabs onto your door with elastic banding sew into the outer edge. Fit really well on a Grand Cherokee. I purchased two, one for the left door and one for the right door. Cross ventilation, WOOHOO! Installed the left door around 9:00pm, installed the right door around 9:15pm. Yes, the poles were difficult to bend but not impossible. People camping near us were impressed. BUT at 8:00am and approximately 8:15am, I heard an unusual cracking/breaking sound. First the fiberglass pole on the left door broke. Then the fiberglass pole on the right door broke. It's like they had a 11-hour self destruct sequence built into them. Can't recommend the product. If it worked it would be awesome. It doesn't work, at least not for very long.
