The Monkey Mirror is a Made in the USA product that has become a favorite accessory of mine.
I’ve used so many other handlebar mounted mirrors that all seem to vibrate too much and are always getting smacked around during bicycle transport and storage.
The helmet mounted Monkey Mirror gets the mirror off your handlebars and onto your helmet resulting in a virtually vibration-free mirror. It does take a little time to adjust to using the Monkey Mirror but honestly, once you’ve adjusted to it, you won’t want to be without it. It’s out of the way but always there when you need to take a quick glance at what is approaching from behind.
It has great clarity and can easily be adjusted to fit your helmet while requiring no tools at all to install.
You can find it online directly from the seller by searching for Monkey Mirrors or just going to monkeymirrors dot com.
