Thanks alot for the review.
We had many conversation with customers and potential customers after the product release.
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 luck is that we chose QR code as the only communicating method:no automatic transfer,all the information exchanging is 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 an 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 an 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.

2 product size and product line
HB02 will be a thinner,lighter and cheaper product, but with less safety.
Our product positioning: HB01 for relatively high-amount customers;HB02 for realtively low-amount customers; and special solution for ultra-high-amount customers.

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