I bought a Yubico key once. The thing was so cheap that between the time I set it up and the first time I actually had to use it, it had disintegrated just from sitting in my pocket every day on my keychain. The plastic was brittle and fell apart piece by piece until eventually the electronics fell apart too.

I've had two on my keychain for years now. One of them maybe 8 years and the other one a little over 3 years. Zero problems with them so far. They still work just fine.
