Memory BOX Pro 2.0🔍 Last analysed 8th December 2021 . Bad Interface
The design of the device does not allow to verify what is being signed!
As part of our Methodology, we ask:
Can the user verify and approve transactions on the device?If the answer is "no", we mark it as "Bad Interface".
These are devices that might generate secure private key material, outside the reach of the provider but that do not have the means to let the user verify transactions on the device itself. This verdict includes screen-less smart cards or USB-dongles.
The wallet lacks either an output device such as a screen, an input device such as touch or physical buttons or both. In consequence, crucial elements of approving transactions is being delegated to other hardware such as a general purpose PC or phone which defeats the purpose of a hardware wallet.
Another consquence of a missing screen is that the user is faced with the dilemma of either not making a backup or having to pass the backup through an insecure device for display or storage.
The software of the device might be perfect but this device cannot be recommended due to this fundamental flaw.The product cannot be independently verified. If the provider puts your funds at risk on purpose or by accident, you will probably not know about the issue before people start losing money. If the provider is more criminally inclined he might have collected all the backups of all the wallets, ready to be emptied at the press of a button. The product might have a formidable track record but out of distress or change in management turns out to be evil from some point on, with nobody outside ever knowing before it is too late.

Private keys can be created offline - ❓
From this video, it would seem that the Memory Box serves more as a BlueTooth enabled device to back up the StartEOS wallet.
The StartEOS help files redirect to another domain, yuque.com. It is a Chinese language site.
Private keys are not shared - ✔️
From Yuque.com, we have some clues on how the Memory Box handles private keys:
Translated via Google Translate:
Friendly reminder: The Memory Box hardware wallet developed by Start stores the private key separately in a security chip, which is completely isolated from the network. Because it does not touch the Internet, it eliminates all methods of network hacking, and it is one of the most secure wallets at present.
Device displays receive address for confirmation - ❌
The device does not have a display.
