Really cool concept! I guess we have found the lower bound of how cheap we can make something that holds your keys. Good luck making something cheaper than $10.
Two things i noticed:
Seed is generated and shown on the host device. Bad idea for obvious reasons
Password is entered on the host device. Also bad idea for obvious reasons
I don't think there's a reason why both of this couldn't be handled by the device itself - so maybe something for a future update! Even a Jade will be orders of magnitudes more secure, but also 6x as expensive.

This is based on the LilyGo TTGO ESP32 microcontroller, which has bluetooth and wifi, and made in China.
Cool to tinker with, but I wouldn't put large amounts of money there.
