Hi Mr. McNacho. This is the one I have. It drops into two handle bar thingies and is tightened with a couple of thumb screws. I can install/remove it in ten seconds. Really. It is about a six mile ride to where I like to ride. I use the screen there and back. I leave it next to the trail with a note and so far no one has taken it. On the way back I pop it on and am home in a flash. In winter when the temps drop into the 50's it is nice for going into town for bike nights.
It does not like to go over 55mph. In headwinds you know it. But for occasional use it is great. The handle bar thingies are totally unobtrusive.
