I bought Qumox normal, but after worries about the picture quality, I was refunded! so I rebuilt my command but finally taking QUMOX WIFI !! it is great! it's on, it is best with Wifi since we rarely keeps the camera in hand, so for framing etc .. it's perfect! I try the wifi connection with my galaxy note 3, I do not happen and following forums on the official website of SJcam, so I made the update, and everything works perfectly! the image quality is great! good value no complaints! I tested it in the sun at the moment and it works very well! I even put the protection box in water in a bowl overnight supported under water, and cotton interior just to check for leaks, and no worries! I should just go about it sometimes several times to open the cover of the box as the system seems to be stuck but otherwise no worries! I recommend product
