I ordered one of these from Amazon, arrived in 2 days in perfect condition.
I wanted this device for attachment to the front drivers window, in order to attach my point and shoot Kodak digital camera so that I could video through the windscreen of my car whilst driving.
With the extension included in the pack, the camera can easily be positioned facing forward in a way that does not restrict my vision and clears the front pilar.
It is quick to attach to the window and stays there for hours without falling off. It is easily removed and can be adjusted so that the camera is in exactly the right position and within easy reach to both see through the camera screen and to start and stop the video.
The results are very good, day and night, when I will leave the video on for whole journies of an hour or more.
This set-up using a digital camera is better than using an action cam which I have tried with disappointing results.
This product sticks well to glass, but not so well to the smooth plastic on the dash, where it fell off after 5 minutes when I first tried it on that surface, not tried it on any other surface, so can't comment.
A well made product that deserves 5 stars, price is reasonable too.
