This mirror is a life saver , not heavy and very useful .Highly recommended product .
I ride a recumbent bike, and want to be sure of what's going on behind me. I tried helmet mirrors...useless. wrist mirror? Perfect!
Easy to adjust and you don't have to take your eyes off the road. What an ingenious invention!
Seem like a good idea. product is of good quality and is as described. I did not get vibration in the mirror when using it on my wrist.
Just be a little openminded on where the sweet spot is and I promise you that you will learn to love and rely on this rearview mirror for all of your cycling needs.
