I just tried to order one. My credit card got charged twice as I attempted twice, got errors on their website, and the customer service rep Rachel in the online chat is behaving highly unprofessionally. My other attempts with another card were flagged as a possible fraud - obviously, their reputation among the credit card processors is not stellar. I think I'm done with Yubico and will be waiting for my Titan key from Google and consider the open-source SoloKeys as well. I think I've invested enough money in Yubico and what I'm getting back is not enough to justify the costs of this luxury. Their shortsightedness not to offer NFC on the USB-C version and to make the 4C/5C Nano so extremely hard to pull out is a clear sign they no longer are a good choice. And for quite some time, they haven't been the only choice either.
