Jiusion HD 1920 x 1080 DVR Sunglasses Camera Dash Cam with Photographing, Video Recording Function Automobile Data Recorder (Cam+8G)

It's cheap, and that is the best thing I can say about it. You really don't know when you're recording or not, and I tend to stop recording instead of start, or start when I meant to stop, resulting in videos of things I don't care about and missed moments. For some crazy reason, if you charge it while the memory card is installed, it thinks you want to record and does so automatically. You have to take the memory card out to charge, or it will fill up the memory card. Then when you want to use it, you can't. I ended up getting a different camera. The video quality in bright sunlight is actually pretty good, as is the audio. Without bright light though, the video quality is quite bad. The rubberbands break easily, though they do include some extras. I would not purchase this again and will probably only use this one as a backup.

I've tried other devices like a body cop cam which died after the 2nd use and 5 spy pens. I returned one pen because it didn't work at all and 3 didn't record more than 35 minutes with a 32 GB chip. The other (the cheapest) recorded 1.5 hours. A second of the same model took 35 minutes. None would function while being charged. The eyeglasses cam blows them all away.With only the built in battery I got 30-35 minutes of video. But I discovered that it will record while charging, a definite plus since most such cameras will not. Hooked to a battery pack I got almost 4.5 hours with a 32 GB chip installed. That's all the chip would store. It fit snugly on my eyeglasses. It isn't exactly a secret spy cam, but I'm not using it for clandestine purposes. I suspect that it might be mistaken for a Bluetooth device.It's much easier to understand it's operations than the pens because it vibrates when it's turned on and off, and when the video and still cameras begin operating. The pens only had small lights which I found hard to understand and couldn't see while in operation because the lights were hidden against my body..I'd buy another one and very well might.

The ratings are given on the basis of what I paid for this. Of course, this will not give the quality of a nice video camera, but for the price, this is pretty darn good.It is light, and easy to use. A nice feature is the vibration it makes when pressing the buttons, because when attached to my glasses, there is no way to see the LEDs. I would like to have a longer run time, but it is what it is. With a larger memory card, it will run longer if plugged into an additional battery.

It says: "Comes with a free 8G micro SD card"No card arrived with the product!

I wish I could find these. Whoever makes them have stopped making them...I can't find them stocked anywhere. I bought one maybe 2.5-3 years ago and the battery will no longer hold a full charge. I should've bought 2-3 when I found out how practical it was.I use it when I go to the range. I record myself shooting so that I can study the things I'm doing wrong when I get home. I've used several other action cameras for range use (GoPro 3 & 4, Astak, Mobius, and Cube+), and this glasses cam is by far the best. I can wear it and not even notice it while shooting. When I shoot, it shows footage from 1st person perspective. It's good enough so that I can even look down the sights as I'm shooting.It is not good if there's no good light. It works extremely well in direct sunlight or high wattage indoor lighting. The sound isn't good but it isn't bad, either. The only thing I don't like about it is that it's difficult to pre-screen (like checking to see if the camera is positioned correctly), but the Mobius was the same way while being much larger in form factor. The video footage is in 1080P.The Juision does work while it's charging, so I'll use it with a long charging cable until it stops functioning.
