I am Asian and I always need sunglasses with adjustable nose pieces. So I decided on this pair over others. The arms are a little thick and may annoy some wearers.
The sunglasses worked out of the box after I put in a 32GB microSD card.
Turning on and recording was pretty straightforward. Quality is good enough for identifying what you're seeing but definitely not the quality of your average mobile phone.
I don't know if I'd go on the water while wearing these. The cover for the USB and SD card ports do not seem tight enough to keep out the water.
Setting the date/time is a little more complex than the instructions imply.
- I had to copy the time.txt file to my desktop and edit the date/time on that saved file.
- While the sunglasses were connected to my computer, I formatted the SD card. Their recommendation was FAT32 and 64kb size.
- I copied the edited time.txt file back to the blank SD card. I only powered on and started recording again once this was done.
Even after these steps, the file names didn't have the correct date/time until after a few recordings.

My glasses record for 5 minutes and shut off. I push the button a second time and they record for 5 minutes and shut off again. How do i get my fully charged glasses to record for 30 minutes?
Also, i am unable to change the date and time. Help please?

I have a sorta big dome, size 7 1/2 to 7 5/8 and they fit a little snug but not be uncomfortable. Can't say much beyond that as I lost the SD card before I watched the video I filmed.

This is a great camera and I highly recommend it. My primary use case for this is riding to work and back and having a video log in case I get hit by a car and need evidence for insurance. Also, I can get home at night and show my kids how intense it is to ride your bike around the streets of San Francisco.

The glasses are comfortable; you really don't notice you're wearing them. However, both pairs of these I've had the right arm of the glasses sits lower on my ear than my left. Enough that the video is angled noticeably. I compensated by taking a small dowel rod and using electrical tape to make the right arm wider so that it sits a little higher on my ear. Problem solved. Looks a little janky but does the job. It is possible that it is in fact my ears and not the glasses that are asymmetric so I'm not going to knock any points off for that.

At a certain point my first pair of glasses broke. I don't know what happened. It just stopped taking video. It would record a couple seconds and then stop. The battery was fully charged. I tried a different SD card. Nothing worked. I contacted support and they sent me a replacement. It was encouraging to see a company stand by their product like that. I'm grateful to have a new pair of glasses that works again. Full disclosure: they said they would appreciate if I would give a review of the product on Amazon. I am doing that now. I'm under no obligation to give it a high rating. What I'm saying here are my genuine thoughts.

I am going to pick on one minor thing though. I know it is advertised with this product that the camera has a down-tilted bias. That's fine, but like I say my primary use case is riding my bike. I *am* kind of high up, looking down, and the camera is still tilted too far down. Unless I'm looking up a little bit, you can't really see what's going on in the video very far ahead. It would be so helpful to have some kind of mechanism to change the angle. It'd even be worth making a Pro version of this camera with this feature and charge an extra $20 for it. Just a thought.

Overall, great glasses and camera.

I purchased these glasses for my 10 year old son for Christmas. "Spy" glasses were the only thing he could talk about, dream about, or think about before Christmas. I looked at a few models out there and liked what I saw with these. Reviews appeared generally good and the price was right. I've been very pleased with these glasses. They come in a nice protective case and are easy to operate. We followed the link provided by the seller to learn about the operational aspects and set up. All very easily understood, infact my 10-year old was able to get his glasses working correctly on his own. We've been downloading the video to a laptop via the SD card and not via a usb connection. We've had no issues at all with downloading videos and all the videos have been great. I've been very happy with the quality of the video as well. Other reviews have mentioned that but I wasn't sure what to expect. This has all been a plus from the beginning until now. To top all of this off, I contacted the seller about some replacement clear lenses as my son isn't a fan of the tinted lenses. The seller was quick to respond and very kind. He immediately sent my out a set of clear lenses as a gift. Thank you KAMRE. Excellent support and assistance from this seller from the very beginning.
