Pros and cons

Pros

The listed 36 GB storage and 4800-hour recording capacity are suited to keeping many recordings on the device, subject to the recording settings behind that capacity claim.
A built-in stereo microphone and 3.5 mm headphone jack provide an onboard recording and listening setup.
USB Type-C and claimed OTG transfer offer a route for moving recordings to a computer or compatible mobile device.

Cons

WAV files can take up more space than compressed audio, and the listing does not state recording bit rate or quality settings.

What to know before buying

The claimed 4800-hour capacity is not accompanied by recording settings, and the listing does not specify battery life. Its noise-cancellation and 360° recording statements are manufacturer claims, not measured performance. Confirm the supplied OTG cable and compatibility with your phone or tablet before relying on direct transfer.

Only aggregate rating information is supplied, with a mostly five-star distribution but some two-star ratings. This suggests favourable overall ratings alongside some less-satisfied experiences, but does not identify what prompted either view. The ratings cannot establish whether the claimed storage capacity, noise cancellation or transfer features meet a particular buyer’s needs.
