the circuitry looks amazing, but tbh, the plastic housing feels cheap and makes me afraid to drop it--I think it would split in half if it were dropped on the floor.
It does not come with a MicroSd card. 64gb card is the preferred size. If your Q1 doesn't recognize the card you have to format it from within the unit.
I can see alkaline batteries being an issue if someone stores this for a long time and they leak on to the device. User error, but could that render the device useless and the important date inrecoverable?
I've had mine about a week now and absolutely love it. Very solid product. It's only my 2nd HW wallet and have never used the Mk.4 so I can't compare it to that. I switched from Tangem to Coldcard Q.
