WEST BIKING Anti-Glare Handlebar Bike Mirror 1pcs, Left Side Bike Rear View Mirror With Retractable & 360 ° Adjustable Lens, Foldable Bicycle Mirror For 20-23mm Handlebar

Flexible, adjustable. Good visibility.

I am generally happy with this rear-view mirror for bicycles. It is the best that I have tried so far. I have had two previous ones that kept changing position as I rode and were basically useless. So in desperation I thought I would try this one. The best thing about it is that it stays in place, it is sturdy, and the movement of the bike doesn't make it shift. It is fairly easy to move the mirror itself on the arm as it has a ball-and-socket joint.However, the mirror is kind of tricky to install on the bike handlebar, and it doesn't come with installation instructions. It does come with a little wrench for removing the screws for installing on the handlebar and changing the position of the mirror arm. You can't move the whole arm back and forth without disassembling it. You have to take it apart to change the position. But once you figure out what position you need, it works great. I'm glad I got it on sale, though.

100% Better than the first mirror I bought the view is crystal clear has glare protection easy to adjust and attach to the bike would definitely recommend.

I bought two of these, one for my wife's bike and one for mine. They mount easy enough and are big enough that I can see behind me pretty well. They don't stay in place after adjusted though. There is an adjustment at the base of the mirror where it meets the support leg. This lets you adjust the mirror up, down, left and right. There is also an adjustment that lets you make the support leg shorter or longer. I had to make it about as long as it would go and there is a bit of wobble with it if it is extended that much. It's a decent mirror but I wish I would have paid a bit more and bought a better quality one.

You don't know how many times you look around to see if the car is coming behind you. And you wiggle your wheel and go off in a different direction. This helps so much you just glance and you can see everything in back of you. The instructions for putting it on we're kind of half backwards but installed it so the stem came up and my side of the handlebar, if that makes any sense, so it wouldn't interfere with the cables for the brakes and gears. Nice bluish tint not sure if that's going to come off or not. But this really really helps get one

I’ll start by saying that the antiglare coating on the mirror itself is rather nice. Especially if you live in an area where you would probably be hit by sun glare all the time. I bought this because I was needing a better mirror than the one that originally came with my bicycle. Unfortunately, this was probably the biggest case of get what you pay for that I have ever had.First, leave the construction of the item itself. The item itself is made out of a fairly flimsy, feeling type of ABS plastic. The only metal portion of it is the little turnbuckle or whatever you wanna call it to lock in how far you want the device to telescope out. And even then it’s a very short amount of distance. I was never able to get it where I felt it was far enough out to be useful.Another issue is the little. I guess you could say cloth part that holds it onto your handlebars is very small. And if you have wide handlebars like mine, does it likely will not fit.Finally, there’s the fact that it just feels like there was no effort in actually making the frame for the overall mirror. The mirror itself is fine. But everything else about. It was awful. Went back the very next day.

The only thing i coulnt find an option to buy just the right side like they have for the left . I am blind in my left eye.

More true to size view of rear coming cars. I like it better than the round ones. Adjustable to extend past blind spots. I might buy another one.
