Thanks! I wasn't aware of those, so I watched their videos and read their FAQ.
The KeepKey seems very similar in operation to the Trezor. The differences are that it is much bigger physically, and has a bigger display; It is not supported on mobile devices (e.g. Android, but I suppose if you run Windows or Linux on mobile device that would work); It also seems to cost more that the Trezor ($239 from Amazon.com, but it probably is shipped much faster).
The Case Wallet has the advantage of being self-contained, meaning no connection to a computer or mobile device is needed. However, it also requires some trust, because it uses a 2-of-3 key, where one key is stored on the company's server. (The 3rd key is recommended to be kept with Third Key Solutions, a 3rd party, but you could also generate and secure it yourself.) I'd be a little worried about the "lifetime" GSM chip, or the fingerprint access to their server. The big problem is the big "SOLD OUT" button at the top of their web site. A
TechCrunch review says the price is $199, but who knows what it will be if/when they get more in stock. Also, the name of their product makes it difficult to find in a web search.
