My job requires me to document site visits so these have been handy. I just wear them and press the button. Nobody asks questions because they look like regular glasses. Video quality is sharp in daylight but average in low light. Battery lasted me a full site walk. The memory card slot works fine. Overall these do what I needed them to do.
I've had these for about three weeks now and use them for recording my lectures. The footage is clear from the back row and the mic picks up the professor fine. Battery dies faster than I'd like, maybe an hour and a half. Still, it's been useful and nobody notices the camera at all.
These are pretty neat for the price. I didn't expect much but the video is actually good. The glasses feel light on my face. Charging is easy with the hidden arm thing.
Honestly thought these would look bulky but they're just normal glasses. Recording is smooth and sound is okay. Took me a minute to figure out the button.
