Review title: It takes some time to find the right angle
Product review: It works great for bike with upright riding position, such as cruiser. But with MTB and road bike which rider's upper body leans forward, you would see your shoulder fills half of the mirror when you look straight forward. The mirror is at the far left end of peripheral vision, it's difficult to focus with both eyes.To see what is behind me on a MTB, I bring my upper body upward a bit and close right eye, then turn my head at 11 o'clock position and scan it with left eye. For me the reflection comes in focus immediately when I scan it with one eye. That works for me, it's not a bad workaround. Of course, I always turn my head to look back and use hand signal before I change lane.
