Qumox Wifi SJ4000 Original, usable without problem with the application to connect with Android (SJCAM HD), more than satisfactory result in video, the device heats a little during large transfers, the sealing box worked well for taking pictures / videos at the beach, rather sharp images even under water :), night video is decent (more than the picture), taking the sound is against a little low, especially with the box, a good device for a reasonable price.
