From a cryptographic / system security model perspective, I have to flag any private key seen by a third party as 'compromised'.
Everything about bitcoin supposed to be trustless, a reason not to use the wallet. It is just a paper wallet and nothing more. Not even the cost, but the private key and passphrase that are generated by another people.
I don't have anything against paper wallets, and not even necessarily against collectibles with embedded private key, but this product is clearly portraying itself as a hardware wallet or even as a better alternative (based on which subforum MrSlattery posted it in, the grift worked), which it most definitely is not. That's why I am so clear about their claims / comparisons and why they are wrong.
I do not see it on there website that it is an hardware wallet, this is what I found on their website:
The world's first multi-currency non-electronic physical cryptocurrency wallet, designed for everyday people. Use Ballet to easily store Bitcoin and other
Some sites may be calling it hardware wallet, which is very wrong.
But I do not like this on their website:
No Mnemonic Phrase
REAL Series wallets come ready to use out of the box. Just scan the QR code to deposit crypto to it. No need to worry about writing down and storing a seed phrase.
