I just received my glasses, charged them fully, put them on and started recording while playing outside in the rain. These are the only camera glasses I haven't had to protect from the rain. The video quality is amazing even in low light conditions, the microphone works great and the video and audio playback is fantastic. The instructions are well written. It was easy to change the date and timestamp and you can easily change the video quality if you want, but I have no idea why anyone would want to record at a lower resolution. Although I like them, they are very comfortable. And taking pictures while recording is great. P>S: I had a problem with the first pair of glasses I bought and I emailed the company and they responded promptly and were very helpful, they went through everything for me via email what they could. I am very satisfied with their attention to the desire to please their customers. and i emailed the company and they replied very timely and were very helpful they did all they could for me via email.
