Good Coldcard Mk4 (5 devices tested)
+ Many security features such as duress pin and keypad scramble
+ Might seem complicated or overwhelming, but it is great for learning, and you quickly find your way around
+ Bitcoin only
+ Dice rolls for entropy
+ Overall good build
Bad Coldcard Mk4
- Initially the SD card got stuck, rubbing on the plastic casing. Of the 5 devices tested, had the issue on 2. After some usage it seems to no longer be an issue
- When using the magnetic USB adaptor, you cannot slide the protective cover on the back
- Controversial topic, but the code is not open source. Though not an issue for me, and they are free to choose the license they want, the discourse with the FOSS community often seems misleading and aggressive; unnecessary
Neutral Coldcard Mk4
~ Seems with firmware updates, menu items often move around, creating confusion
