They are craps.
Trust me.
It is very possible the seller got these from some factory in China, where they are sold around $30.

Been looking into picking up a smart mirror. Wanting to get a full replacement (pass on a strap-on) with a built in dash camera and and extra camera for forward parking (need manual enable button). I seem to keep circling around back to http://www.auto-vox.com/Products/show/cid/1590/id/78.html. Anybody got one installed and if so how well is it working out? Or if you have a different brand to suggest I am open to suggestions.

Since its been a couple years and no replies on this thread I might as well bump this thread for attention.
