It's one of those freshnel lenses you glue to your rear window to act as a fisheye lens. It's actually surprisingly good. I can see the ground about 1.5m (5ft) behind me. I wish it would reach my rear bumper as that's what I'd like to see but this helps!
Also, I took the picture with a poor man's smartphone - my apologies.
This is better than the time I called myself on FaceTime and stuck one phone on the back of my truck so I could hook up a trailer by myself
THAT'S SICK
does it last??? Being stick-on doesnt give me a good feeling
Love the simple elegance of it. It just works, no subscription, nothing to break, nothing to fix. And all the money you saved can be saved or spent on what is important in life.

I remember those from ages ago used for very similar or maybe even exactly the same purpose. One of those analog solutions that went the way of the dodo ever since everybody and everything has a tiny portable computer...
It makes looking out wider, bit that means looking in would be more focused. Careful it doesn't light your car on fire in the sunshine.
I saw one of these on the back of an RV
