How does it compare with Trezor? (The price is WAY less than Trezor's .)
Trezor uses its display to foil keyloggers that try to steal your PIN, and to display the destination address to prevent address substitution by malicious software on the computer.
The price is really low, I don't think I would trust them, but with enough feedbacks they could take Trezor's first place among hardware wallets.
