I bought four yubikeys back in 2012, two pairs as recommended - one in use, one backup. At the time Yubi had a video up of their keys being run over and otherwise maltreated, and still working.
One of my keys failed spontaneously after a just few weeks in my pocket, on a ring with my other keys.
I decided to stop using yubikeys. A password manager has worked very well for me ever since.
