Whoa.  Never buy a closed source hardware wallet bought from a third party.  Trying to save a few dollars could mean you buy a device that's been tampered with, even if it's sold as new.  I wouldn't even buy an open source hardware wallet from a third party.

Maybe you're thinking "Hang on!  You said to buy a Yahboom from AliExpress!"  The Yahboom is not a hardware wallet.  It's a mini computer that runs micro python & can be used for any purpose.  It's not a hardware wallet until you load hardware wallet software onto it.  At some point, I may buy myself a backup Yahboom, but next time, I'd buy it with a robot kit for the fun of it.  When I want to use it as part of a robot, I'll flash the robot code onto it.  When I want to use it as a hardware wallet, I'll flash Krux onto it.  It takes less than a minute to flash Krux onto one of these devices.  You download Krux from Github and follow the instructions.  Or, I think they have an installer too, but I just run a command in Terminal to install it.
