[LEAKYSEALS951]

I didn't read the responses, but, I've ridden a bit, and been run over by a car (cut across my path from the front, not from behind). Cost me a hip, and probably long term, my leg.

I have tried many versions of handlebar mirrors, but prefer a helmet/or glasses mounted mirror. When something comes up from behind, you can determine quickly if they are giving space or not. If not, it is a lot easier to track them by having the mirror on your helmet so you can watch exactly what they are doing by a slight twist of your head, and steering your bike independently of worrying about keeping the car in your handlebar's mirror line of sight.

It's like a heads up display/targeting system in reverse.

On the open road, I would not ride without a glasses/or helmet mounted mirror. It is a little more finicky setting up than a bar mount mirror, but allows me look at what needs to be looked at.

edit- I looked at the amazon link. I have the #2 setup, #5, and #25 setup. I use the 5/25 setup exclusively depending on which set of glasses I am using. The #2 setup is in a drawer out in the garage.
