Thanks alot for the review.
We had many conversation with customers and potential customers after the product release.
From our angle, HB01 is not a prototype, it's absolutely safe both theoratically and pratically. But we understand that from customer's angle, it IS a prototype, because it can't answer many questions from customers' side.
Then we suddenly found that we've put ourself into a pitfall:a good person have to prove by himself that he is a good guy.
As you know, to make a safe, easy of use, affordable hardware wallet is already a very hard job, self-proving is an additional work and maybe even harder.
But , to be responsible for our customers, and to develop our business, we WILL do this.
One proof we've already done and we feel very lucky is that we chose QR code as the only communicating method:no automatic transfer,all information exchanging visible, information can be analysed by 3rd party software.


Answers for some questions:
1 importing a wallet file to Hardbit .
Importing existing wallets is unsafe from hardware wallet's point of view. Our idea is to provide a once-send-all dedicated online software, for those who's Hardbit is lost or broken. I.e, import the backup wallet file to the software, input a target address(recommends an address created by another Hardbit),input password, and the software sends all the Bitcoin in the backup file to the new address. This software will be available soon.
And , we will disclose the wallet backup file format, so that somebody can make a third-party software (even a wallet software) to handle our backup.

2 USB connection
Any automatic transfer method is unsafe from hardware wallet point of view. Because even we are good guys, we can't guarantee that a super-smart hacker can find way to invade our system and steal the private key.
For playing and testing it, you can connect it to USB. But for real storage of Bitcoin, please keep it away from USB. We've provided charging wire and plug.

BTW, thanks to the Bitcoin price surge, we've lowered the product price to 0.269BTC.
