Mirror extensions for 2014 Volkswagen Touareg
What are the best mirror extensions for a 2014 Volkswagen Touareg? I installed a set for our maiden voyage and one flew off halfway through the first leg of our trip. I don't recall the brand, but the attached photo gives an idea. These had dual ratcheting straps that tightened a pair of rubberized pads. I was told these were the best in class, with lots of adjustability and they did seem suitable for my mirrors. I took a long time adjusting them just right and they were snug, so I was really surprised when the passenger side extension jettisoned itself and shattered as we were cruising along at about 50mph two hours into the trip. Any advice appreciated.
