It?s such a great design idea, but so poorly executed. Now I have to purchase another one for my husband! I have a full suspension on the bottom and my road bike up top. i returned them, and purchased s new pair. They hold up both bikes that I have without an issue. Anyone with a mechanical mind can figure it out, but I dont understand why there is no picture of it in its place. And it is ridiculously easy to assemble, and sturdy too. not only does this add style and color and protection to my airpods case. On the Brown pair, you can see gaps and shadows between the shoe and my foot. I looked all over for something that wraps around/stays put when moving, is small/light, is blue-tooth AND has both microphone and headphone (I need both to communicate with older adults and kids).
