Has anyone used the RVM (Rear View Mirror) sold by Flashback (near the bottom of the page)? If so, does it work well? I'm looking to use this with sunglasses (Tifosi Stelvio), so I'm not sure it will fit, but you can't beat the price. I had a helmet mounted mirror but I feel like an idiot when going for road rides (only one helmet).


Here's the description and photos:

The mirror is unbreakable and backed with high-intensity reflective material.
