Sprintech Racing Bike Rear View Mirror - Lightweight, Fully-Adjustable, & Vibration-Free Convex Mirror with 9 Layer Chrome Coating & Shockproof ABS Shell for 20 mm Diameter Drop Bars by - Red

This is brilliant product for road bikers. Very good back view and much safer rides. I just bought it, so can't say whether it get scratches easily or not, but based on the review from others, I always try to make sure it doesn't get scratch.

A very neat product which is straightforward to fit. The view in the little mirrors is wide angle but good enough to see what is happening behind on either side. Much better than trying to look over a shoulder.

Brilliant get a clear view behind without having to upset my rhythm Only Niggle They do scratch easily

Both mirrors had scratches on them in the box that didn't buff out. Not great for something new and fairly expensive. Mirror is easy to install, adjust and doesn't vibrate loose. Also gives a good view of traffic.

I have one of these on each side of all my bikes (3). They are great for safety, which is why you would buy any mirror, they don't get in the way in any direction (top or sides) and they do the job they are meant for. Some mirrors stick out the sides and make the bike wider so fitting the bike through a tight space can become annoying. Others take up valuable space on your handlebars. These are out of the way, easily installed in about 5 minutes and show everything behind you. The reason why I like having them on both sides is because sometimes when rounding a curve in the road, a car can actually be on the right in your rear view, and it can also be good for locating a fellow rider behind you. They are a little pricey but their lack of posts and other contraptions mean they are much less prone to breaking or other damage and I highly recommend them.

Great, very clear to see what is coming from behind. It helped me a lot. A little bit difficult to install into the handlebar but finally, it is done.

Not the clearest in rear vision. But...I love the fitting and view. I added some black tape to ensure bouncing over rail tracks and pot holes didn't change angles. I have one set for when on upper bar and one set for drops. So punch line, I tried other types and these do just what I need. See cars and their lights approaching. Update: June 2021. These are great. I have ridden over 5000km with them in semi urban and country roads. I look down at my Garmin and catch a glance on things behind me. Changing lanes or turning, you quickly check for head lights and do a shoulder check for safety but you have already prepped for the turn because the mirror gave you warning of options. To protect them I shaped some bubble wrap and tape when I have to load the in a car. Recommended.

I was worried it would be too convex and cars would be on top of you before you saw them but its a good blend between field of view and seeing far enough behind you. Car with DRLs are appreciated! Easy to adjust and stays unless you bump it.
