Yes, the wait list got super crazy at the end of last year. I picked up 4 maar the beginning of 2017. They are much more secure than any other option, have you looked also at Trezor?

The problem with all the other wallets are that they are only as secure as your device. I only use them as a hot wallet with minimal amounts for quick use (hardware wallets are a bit more of a pain to use).

Exchanges are only as secure until the day they are not. Don't trust them with anything unless you are day trading and even then...
