Somewhat personal ancedote, but I've had pretty good experiences with Yubikeys. I've had one on my daily keychain for over a decade now. Its been run through clothes washing machines too many times to count, I've left it out in rainstorms, its been baked in the sun on hot summer days multiple times, its been dropped in pools, its been run over by a car, I've dropped it some pretty significant heights while hiking. It is still working just fine. That and a PNY 16GB metal keychain flash drive have taken a ton of abuse and are still working just fine. Other than a higher melting point or ability to take high energy RF I don't imagine there is much more abuse a traditional metal key would have compared to what I've done to my Yubikey.
Maybe it’s the old USB version? I haven’t had so much luck… I had a couple of nanos, and those broke pretty quick. More recently, I switched to a usb-c version…. And while it still works and stays attached to the key ring. The plastic housing has broken already. I got a corp branded one now, that I’m trying and seems a touch more robust
I've only had the full USB-A style ones. Every device I've had that I've needed a yubikey with has either a USB-A or supported NFC. The >1 decade device is a Yubikey NEO, I recently got a Yubikey 5 USB-A variant and also have one of those FIDO-only blue Security keys in USB-A.
What kind of failures did you have for the nanos? They just became unresponsive? Did they suffer any obvious physical failure or any particular kind of event cause their failure?
