It was easy to follow the instructions for pairing with my phone and the buds stay in place well with the curved attachment. They feel like some cheap knockoffs. The pair my 6 year old wore last year had been through 3 kids. Finding seat cushion that fits I have not found one yet,using pillow works for now hope my rear gets use to this one it is not that bad I am 64 and out of shape with bad knee to soon to comment on durability of bike or myself. Not the strongest, but still good. I ride with my almost 3 year old daily, for school drop-offs. Debido a esa excelente experiencia de durabilidad decidí volver a comprar un mouse Razer. I love how adjustable they are as I have wide feet. It?s not designed to hold barbells or auto engines. Save Yourself the Hassle and Buy the $33 Pair of Crocs sandals on Amazon, dont buy these on impulse to snag a "Seemingly Good Deal" .
