Sixmou i3
Score: 67/100
Intepoll Mini Action Camera
Score: 66/100Rankings
The Sixmou i3 is an ultra-compact 4K thumb-sized action camera praised for its tiny form factor and versatile magnetic mounting. Its battery life at 4K is limited and the supplied waterproof case is fragile, reducing suitability for rugged activities. Best for casual users seeking a discreet POV recorder.
The Intepoll 4K Mini Action Camera is a pocket-sized, waterproof cam that ships with 128 GB of storage and a magnetic mounting system. Its limitations include a short battery runtime and a modest 30 fps video cap. It suits casual vloggers and outdoor hobbyists who need a ready-to-go, ultra-compact recorder.

Professional coverage is limited, but a December 2025 Critical Reviews video concluded that while the Sixmou i3 impresses with its tiny size and convenient charging-while-recording feature, it falls short on battery life at 4K, has a fragile waterproof case, and lacks the rugged construction needed for serious extreme-sport use, making it a niche option rather than a best-value choice.
Professional reviewers commend the Intepoll for its pocket-sized form factor, built-in 128 GB storage and magnetic mounting that make it instantly usable for outdoor vlogging and cycling. They also appreciate its IPX7 waterproof rating and straightforward Wi-Fi/app control. However, they criticize the modest 90-minute battery life, the absence of higher frame-rate recording, and the basic sensor, which limit its appeal for serious action-camera users.
Everyday users are enthusiastic about the camera's tiny size, ready-to-go 128 GB storage and the magnetic accessories that let them attach it to virtually anything. The waterproof rating and included mounts are repeatedly praised. The most common complaints revolve around the short battery runtime, occasional fiddly Wi-Fi pairing and reset button, and confusion over the exact weight of the device.
