This is a great camera that I highly recommend. My main use case for this is commuting to and from work and keeping a video log in case I get hit by a car and need proof of insurance. Plus, I get to come home at night and show my kids how hard it is to ride a bike through the streets of San Francisco. Glasses are comfortable; you don't really notice you're wearing them. However, I had both of these glasses, the right side of the glasses sits lower on my ear than the left. It is enough that the video is noticeably tilted. I compensated by taking a small stick and taped my right arm wider so it sits a little higher on my ear. Problem solved. Looks a little edgy, but does the job. It's possible that my ears are actually asymmetrical, not the glasses, so I won't deduct a point for that. At some point my first pair of glasses broke. I do not know what happened. I just stopped making videos. It records for a few seconds and then stops. The battery was fully charged. Tried a different SD card. Nothing worked. I contacted support and they sent me a replacement. It was nice to see the company treat their product this way. I'm thankful for new glasses that work again. Full Disclosure: They said they would appreciate it if I reviewed the product on Revain. I'll do it now. I don't have to give him good grades. What I am saying here are my righteous thoughts. However, I will pick a little thing. I know this product is advertised as having the camera tilted down. That's fine, but like I said, my main use case is cycling. I *am* kind of high, looking down, and the camera is still too low. Unless I look up a bit, you can't see what's happening very far ahead in the video. It would be very useful to have a mechanism to change the angle. It would even be worth making a Pro version of this camera with this feature and charging an extra $20 for it. Just a thought. Overall great glasses and camera.
