As far as I'm aware... they're not actually on sale anywhere. You can only "pre-order" via indiegogo here: https://www.indiegogo.com/projects/cobo-vault-military-grade-cryptocurrency-wallet?utm_source=Website&utm_term=Cobo#/

It is labelled on Indiegogo as: "PROTOTYPE STAGE"

The cheapest pre-order option that they have is USD$299... that is apparently $180 (37%) off the listed "normal" price of USD$479!!?! :o :o :o

Saw it on their crowdfunding campaign on Indiegogo. Not sure if it's sold anywhere else since it's being crowdfunded right now. https://www.indiegogo.com/projects/cobo-vault-military-grade-cryptocurrency-wallet/#/

What the hell? Who in their right mind is going to spend 3x-5x as much for a completely untested and unverified product? All you are going on are the promises of the company. Look at McAfee's Bitfi wallet for how well that has turned out in the past. You can get a Ledger or Trezor, which have both been extensively tested and verified by external sources, for less than $100. I am also still unclear as to how they can promise such security since apparently you have to use an app on your smartphone to send transactions.

Because the transaction is created and signed on the completely "offline" (airgapped) cobo wallet device itself... and you only use your smartphone to scan the QR code off the cobo's screen and then broadcast the transaction. Basically the same theory as an airgapped PC generating a QR Code that you scan with a digital camera and then use online PC to broadcast.

Given that the transaction is already signed, there is no way to actually modify it on the smartphone.

Supposedly, the Cobo has no "interfaces" (ie. no usb connections, wifi, bluetooth etc) to be able to hack it... However, it does have an sdcard slot for uploading firmware... sooooooo yeah. :-\

Makes sense, but I couldn't find that information on their indiegogo or their website. They just keep harping on about how it has military grade durability - because apparently being able to work down to -20 degrees Celsius and being sand and salt resistant is more important that any actual technical details. I'm not sure who is trying to spend crypto deep in the middle of the Sahara or the Antarctic, but given your phone has likely packed in long before then, you wouldn't be able to broadcast your transactions anyway. ;D
