This mirror attaches securely to the visor with no adhesive or double backed tape. It folds neatly out of the way when not in use. The best feature is the ease of adjustability and how well it maintains that setting. I can adjust it so I see just the tip of my left ear and the road directly behind me when I am hunched forward and facing straight ahead. On other mirrors my shoulder gets in my field of view and I need to tilt my head to see the road better or rotate my head slightly to see directly behind me, not so with this mirror. This mirror has a wide angle feature so objects are closer than they appear. I like the wide angle and you get used to it just like you do with rear view car mirrors. The only drawback is the limited helmets it will mount on.
