If you trust any device to generate your seed phrase, you're introducing unnecessary risk for the sake of convenience.

Get a few packs of plastic dice from the dollar shop and roll your own seed. For a 12 word seed with near perfect entropy,
you'll need to do 56 dice rolls. 4 packs of 6 dice meant I could roll 4 words with 1 roll. The last word takes 1 roll & you will choose with the word from the device.

Before you come at me with needing casino dice, it doesn't matter. Analog randomness was solved a long time ago, it's digital randomness I don't trust. Loaded dice are crazy expensive, your not going to find them in packs of 6 for $2.50
