Please make it suitable for iOS. More flexibility = more usability = more transaction = more trezor user.
Trezor Support

Hi,

Thanks for sharing your feedback. We’d love to offer full iOS support on all devices, but the limitation comes from iOS itself, which doesn’t allow the type of wired USB communication needed for the Trezor Safe 3. That’s one of the reasons we introduced Bluetooth connectivity with the Trezor Safe 7, making it possible to support a much smoother experience on iPhone.

The Trezor Safe 3 gives a very mature and well-designed impression. The setup process is straightforward and easy to follow, even for beginners, as long as a bit of care is taken. The device responds reliably and works smoothly with the Trezor Suite. Particularly noteworthy are its support for a wide range of cryptocurrencies and its transparent, open software approach. Confirming transactions directly on the device provides an additional sense of security. Overall, the Trezor Safe 3 is a convincing hardware wallet for anyone who wants to self-custody their cryptocurrencies and values security, ease of use, and a well-thought-out solution.

Balení, doprava, instrukce, setup, všechno na jedničku. Opravdu bezproblémová a pohodlná instalace. A vlastně nemám co vytknout. Snad jen konkrétně můj kus.. je na něm bezpečnostní samolepka s textem, který však i po jejím sundání držel (otiskl se) a šel těžko sundat. Ale věřím že to je ojedinělý případ. Také jsem si s mým trezorem pořídil i pouzdro. Které by však možná mohlo mít například kapsičku na papírek s bezpečnostní frází. A případně mohla být uzpůsobena aby se do ní dal umístit pohodlně také kabel. Nicméně pouzdro je velmi kvalitní a dobře zpracované. Jak jsem řekl tohle jsou jediné nedostatky a jsou to opravdu drobnosti, jinak celý proces ať už komunikace přes kvalitu produktu i pohodlí při jeho nastavování šlo báječně a nemam co vytknout.

What’s the difference between Trezor Safe 3 and Trezor Model One?
The Model One focuses on a more hands-on approach to crypto security with its OLED display and intuitive button interface. Trezor Safe 3 prioritizes security with its Secure Element chip and offers easy usability with a monochromatic screen and two-button input.
