Customer's feedback: "The camera is well built and the App functions great.
At first it seemed that the battery life is too short but after a few rechargings it got better.
The photo quality is bad. The autofocus should be better.
The sound could be better. When you close the door of a car there is a specific sound that doesn't sound good. If you drive and record and the car windows are down you can hear cracking sound similar to the sound of the doors closing. The camera is sensitive to too much light or dark. It would be useful to put a battery power indicator on the device. The indicator could have 4 or 5 bars.
I had to format the memory card twice and later the problem disappeared. If you record in 4K the videos will be in 5 minute segments. I recommend recording in 1080p 30fps because it seems there is no much difference between 1080p and 4K.
If you record in 1080p the video segments will be 20 minutes.
I had to contact the ORDRO to disassemble the headband because the instructions weren't clear. They responded a bit later than I expected but I am glad that they responded at all.
Overall EP7 is a good camera if you don't have big expectations. That doesn't mean the camera is bad."
