What the hell are you on about it's just an affiliate link to the Blockstream store. You know Blockstream, one of the oldest and most reputable companies in Bitcoin. Adam Back is CEO of Blockstream who invented hash cash and POW among other things... Jade is a completely open source hardware wallet. Hardware and software is open. OP asked for suggestions and I gave him mine. That's not spam and the way you talk to people is unbelievable.
