Ebay cheap HD 1080p DVR Spyglasses under $30

I like using Spyglasses, DVR glasses, Video sunglasses, or whatever you like to call them for shooting videos of my RC aircraft and other stuff. It just makes it easy and looking thru the glasses frame helps me to center the subject.

I have marked the inside of some to find the center point of a video by first marking the outside of the sunglasses lens (usually with a circle), referencing where the center of the video is from where I've marked them, and then adjust until it's centered. These seem to be quite well centered out of the box! Not only that but they took good daylight video, indoor video, and low light video. The audio was the best I've had from any of these I've ever had.

The only issue I had is when they adjust for different lighting conditions it very stagey. But for under $30!! I'm not complaining and plan to use these for a lot of my video projects.
