When they came in I was shocked. Installing took about 10 min per mirror, However neither the mounting bolts nor the mounting nuts came with the package, so we just used the ones from the old Mirrors. Sehr schöner schuh und passt sehr gut. We initially werent aware that they lit up but, of course, that was a major selling point for the munchkin. My only wish would be that they took better advantage of the size and increased the vertical height of each increment. It took over a hour to finally come out. However, if you just want an easy to carry, collapsible, over the ear headphone that you dont have to worry about getting hurt, this is definitely the way to go. This spice holder is very nice, but unfortunately I had to return it because it was too tall for my drawer. These look great and are really comfy, and I like that the fit can be fine-tuned with the adjustable velcro “thingy thing” (what’s the part that goes over the top your instep called??). Which is why I was surprised how much I loved the Apple AirPods.
