Got this used device for a steal! It does the job for keeping my conversations private in busy areas, but the setup could be easier. Shipping took longer than I expected, but it was worth the wait in the end.

Mixed Results
This device has potential, but I faced some hiccups in setup. The instructions weren’t super clear, which made it a bit frustrating. Once it was up and running, the privacy features were solid, but I expected smoother experience.
