| Verdict | Skip | Depends |
| Best for | Bitcoin-only holders wanting air-gapped signing | Long-term crypto holders |
| Who it's not for | Anyone buying right now . trust is not rebuilt | Anyone with small holdings . an exchange or software wallet suffices |
| Privacy | Compromised: a 5-year RNG firmware flaw led to ~$116M stolen in 2026; a deeper fix shipped Aug 21, 2026.¹ | Device firmware is broadly trusted, but customer data has leaked repeatedly and a $500M breach lawsuit is active. |
| Support quality | No support evidence found | No phone support offered |
| Public sentiment | Long a favorite among Bitcoin maximalists, but post-hack threads show shaken trust and affected users seeking recourse. | Long-term users generally trust the hardware, but complaints cluster around customer service, app friction, and breach anxiety.15 |
| Biggest gotcha | Verify your firmware version and device batch . deeper fix only shipped Aug 21, 2026³ | Two data breaches exposed buyer identities . expect phishing calls, emails, and even physical threats |
