Verdict
Both providers are practically level in our overall rating (4.7 to 4.8).
The mobile alternative to Tangem, with one real security advantage: its own display, so you verify transactions on the card itself. It is designed to be carried daily; for your main cold storage, a classic desktop device remains the safer choice.
The clear recommendation for cost-conscious open-source fans: modern secure-element protection at a low price. If you want the comfort of a touchscreen, step up to the Safe 5.
