These devices in the pictures look like children's toys, and most know that Trezor does not have a model labeled Mini. I wouldn't worry too much about this, because the Russians, and especially the Chinese, copy whatever comes in handy.
I would worry more about identical copies, which at first glance are hardly different from the original.

Damn, those are pretty close indeed.
I wonder how many people have actually been scammed by these though? Surely the Trezor Bridge software would detect a fake wallet, or do they use some other wallet client? That should be an immediate red flag for anybody.
