Picture is a little grainy but works quite well

These glasses come nicely packaged and at first sight look like a regular pair of spectacles, a little thicker temples than normal, but not so you would notice. Instructions have to be downloaded as a PDF and are of good quality. The operation is simple but you should practice taking videos and photos before you take ones that count. Switching between stills and videos is easy once you have practiced. There is no image stabilisation - not that you would expect it at this price - so you need to make smooth movements with your head taking video and keep still taking photos, making sure your head is not tilted. The results can come out reasonably well if you follow this simple advice and the sound quality is perfectly acceptable. To download stuff, just plug a USB cable in and connect to your computer and you can access the SD card (and you can also remove and replace the SD card, but it comes with a creditable 16MB). Battery life is reasonable, and the glasses are a cinch to charge (a really good quality power adapter came with mine). I've really had a lot of fun wearing these glasses to take video and images and am still learning how to get the best out of them.

Very poor pixilated playback, with split screen and very low definition. Absolute rubbish, very disappointing and not fit for purpose by any description !!!

I am really happy with this product. I am using these spy glasses at my work place for my safety. I am a manager and this helps me a lot with unhappy customers and thieves catch at the time of their criminal act. Voice recording is really good. Camera resolution also amazing. The best thing is that the glasses comes with 32GB memory card. You can set up date and times stamp on the recording. Highly recommended!

i have several of this hidden camera glasses model - they are good and do the job and the Chinese designers keep improving the model through software and electronicshowever they are fragile in the longer term and instead of using what seems to be ABS/PC plastic which eventually cracks and breaks in several places - it would be better if a tough Epoxy is used - they could also be laminated with a hard Silicone for grip and to reduce brittleness from cold environment and chemical degradation

I was able to film in a place where filming is strictly prohibited. The camera is so imperceptible that security didn't notice there's a camera in the glasses!

In good lighting conditions, images look good! It's necessary to avoid very sudden movements with the head so that the image is clear.

With full battery, I was able to shoot for 165 minutes and my friends loved the videos I showed them!

Unbelievable, this is awesome!
