Newlight66 Bike Mirror, Adjustable 360 Rotatable Handlebar Glass Rearview Bicycle Mirrors for Road Mountain Bike (2 Pack)

PROs: Quick & easy install. No tools required. Clear images. Once the mirror position is adjusted for the best view, its position does not drift and holds steady even while traveling down a bumpy road. CONs: Only disappointment is that the mirror curvature (to give a wider field of view than a flat mirror surface) is considerably greater than the passenger-side mirror on a car. When traffic approaches from behind the image in the mirror is so tiny that the traffic may go unnoticed until the car is less than 200 feet ( 60 meters) behind the bicyclist. By then, the bicyclist will likely have heard the approaching car before seeing it. This also makes it tricky to plan left turns in traffic. I added another mirror from a different manufacturer to provide my desired level of safety. If this mirror had a gentler curvature -- like an automobile mirror has -- this product would have earned a solid 5 stars.

The mirror works pretty well. The pros are that it's easy to install, the view is wide angle, and it's adjustable. The cons are that objects are much closer than they appear (just need to be aware of that fact), and the mirror doesn't stay in place all of the time. However, I was able to tighten the mirror joint with an Allen wrench and that helped it stay where I wanted it much better.

Good enough; far better than no mirror. But get the mirror positioned correctly, go for a ride, look down at it... and I need to lift the mirror back into position every single time. And I can find no way to tighten up the mount.

These are nice bike mirrors and I was able to fit one to my (steel) frame to glance it instead of my handlebars; just a personal preference. I’m not terribly big on the rubbery band clamp as employed as it doesn’t take much to throw the mirror off-kilter.That said, the mirrors are a nice size and shape for their purposes, so it’s worth a little effort to get them set up as you like.

a bit flimsy. They work well if you are going slower than 18mph as the wind can move them. They also move easily over bumps in the road. I have to find a way to keep in a fixed position. Good for flat roads and not going fast.

Very easily installed and gives biker a "heads up" as far as overtaking traffic from behind at a glance.Image of a bicyclist behind is quite small due to parabolic mirror but acceptable.

For what I paid they suit their purpose. My only problem is that they move around and I have to adjust them all the time.

Very good simple mirror. A little larger viewable area would be perfect, say a 1/4 to a 1/2 of an inch circumference larger.

Bueno, bonito y barato
