I backed their crowdfunding campaign back in the day. Due to $REASON I didn't test all of them when I got them, but when I got around to it two out of four were broken (the broken ones had USB-C). Their support didn't help at all (why should they? but they could have offered me keys for a better price...)

With that said, I had a Yubikey Neo die for me as well (NFC still worked, USB totally dead) - Yubikey offered me a new key for a discount.

Solo 2 fixed the bent connectors issue. Solo 2 USB-C has supply issues, you'll probably have to wait a couple of months to get one.

solokeys2 is physically better than solokeys1, but firmware is buggier
