I own a Yubikey, and I can see why it has a virtual monopoly. It may look flimsy, but it is on my keychain and I do not bother to baby it. It has lasted for well over two years with little signs of wear. It is also very thin and adds little more footprint to my keychain then another house key. While I do not have it, they also have another one that almost fits completely within a USB slot.

The size of that security key is almost a non-starter to me if I need to keep it on me.

Totally agree on the USB-A models.

On the other hand, my USB-C Yubikey only lasted a month in my pocket before the case fractured and flaked apart. Whatever plastic they encased it in was not up the job of being on keyring. Additionally the plastic sleeve inside the USB-C plug broke and the thing became trash. Yubikey shipped me a new one, but looks to be of the same design. That was last summer. The photos on the website appear to be the same, hopefully they've improved the quality.

Same happened to me with the USB-C key. Meanwhile, my three year old USB-A key that has lived on my keyring continuously shows some obvious wear, but no signs of damage.

Interesting, I have both in my keychain, I destroy all things consumer product usually, but both are fine. 1-2 yrs straight. I do wish other companies would compete in the space.
