I have some feedback to share,but to avoid getting lost, I'll focus on just one for now:

I noticed that when generating the seed on the Seedkeeper, it's displayed through the Satoship app's graphical interface. This could be problematic since it's generated on the user's online computer, which might be compromised by malware or keyloggers. Of course, this risk could be mitigated if the user generates the seed phrase using an offline computer.

I see it's possible to export the encrypted seed (E2EE), but from what I understand, these backups can only be used with another Seedkeeper or Satochip. I wish there was an option to export encrypted backups (as text or file) that could be imported into other software wallets like Sparrow, reducing dependency on a single product.

In a way, I found the product very interesting and would like to acquire it one day as additional options for my backups. However, the price of €25 plus the €19.99 reader makes it unviable for users in South American countries, where local currencies are much weaker compared to the dollar and EUR.

My apologies if I've misunderstood anything.
