It is written there already. Use Trezor, the real open source hw wallet.

For me personally, after talking to LOTS of bitcoiners who are deeply technical and very committed to open source AND still will only use a Coldcard, I'm never going to use anything else.
Call it social heuristics if you want, but I guarantee that 99.9% of bitcoiners (me included) have no idea how complicated it is to keep keys properly secure. If "verifiable source" is the tradeoff required, so be it.

With easily available tools you can extract keys from a trezor one in minutes, this attack has been publicly demonstrated many times. https://m.youtube.com/watch?v=Y1OBIGslgGM
