but guess what? It STILL WORKS. Overall pairing was complete in just a couple of minutes. I will request to refund or exchange the product to resolve this issue. Crocs changed their styles and fit a couple of years ago so I stopped ordering those. Unfortunately, unless you throw away the soft screws this comes with and you replace with stainless, this will fail in under 3 months. The rest of the shelves are for the footwear we wear often. I expect this from Ikea furniture, but not from an expensive kids bike seat. And I have "normal" ears lol I can wear these for hours without my ears hurting. I feel like I?m dusting the floors while I walk.
