Bests & Worsts Reviews from Amazon

This is my third helmet mirror, and it is my favorite by far! It is much bigger and more stable than the others. My other mirrors both had the following problems: 1) small field of view, 2) vibration when going over a bumpy road, 3) angle slippage, requiring frequent adjustments mid-ride. This mirror solves all those problems. The field of view is fantastic. See attached comparison pics. The swivel arm is rock solid. Doesn't vibrate, doesn't move out of place. Best of all, the stem has independent swivel points, each with just the right amount of stiffness to maintain their own angles. So you can swing the mirror out of view when not needed, and then swing it back into view and the mirror angle is still perfectly aligned. Brilliant! I love this mirror!
