First, I will advise you to never the fact-checked that's not done by the crypto community or reputable people like Jameson Lopp, etc. Trezor was once my favorite hardware wallet because it was open source but I don't see it as ultra-secure hardware as you called it ever since a hardware hacker who also happens to be a computer engineer described how he broke into a Trezor One hardware wallet containing more than $2 million although Trezor dev team claimed it an old issue that's already fixed. Besides, Trezor wallet can also open the device by mitigating side-channel attacks trick though this can be done through a physical attack.
