These are absolutely wonderful! I get the impression that these are in fact FAKE Dr. The hardest part was getting the load bar onto the fit pack. Installation was remarkably simple and easy to accomplish for my bars and fairing. Set up was easy, it installed automatically on my PC. It helps me keep up with my AirPods. The app works very well. Its a great charger. One of the best racks on the market and you can?t beat the price! Despite providing tight seal in the ear, they are not painful and I have had moments where I forgot I was wearing them.
