Accmor Bike Eyeglass Mirror, 360 Degree Adjustable Bicycle Cycling Rear View Wide Angle Mirror, Riding Accessories,1 Pack

I couldn't figure out how to get this on the helmet. Duh! It clips onto your glasses and works well. The shafts are thin, and it seems like it would bounce a lot, but the image is clear and you can adjust it in every axis. Very lightweight, ok to wear with a helmet.

I wish the mounting was shorter, to get the mirror closer to my eyes for less shaking and wider field of view. As they are, I had to slide the mount all the way back to where my sunglasses' ear bend began to get the mirror reasonably close; and the longer-than-necessary wire amplified road vibration. But... They work. It takes some adjustment before each ride, and maybe a few times during, since you'll no doubt knock them out of adjustment at least when taking off your glasses. But they really do the trick; you can actually see cars coming up on you from quite a distance with the smallest turn of your head. This is what I wanted...to keep my eyes on the road ahead, while seeing cars and trucks behind, without having to crane my stiff sixty-something year-old neck around like an owl.

I was able to clip this onto my baseball cap perfectly fine.. it's sturdy and stays in place. My complaint about it is that the mirror is so small, its very hard to see things behind you. I wish they either make the mirror larger or make it curved, to give me a wider view of what's behind. So if you walk on a trail, and if the trail turns and bends, and the mirror only shows you straight behind you, you wont' see much of the trail... it will just show the trees that's straight behind. I think a curved mirror will do better.

After a few months of use, the hinge where the mirror attaches is so loose that the lightest gust of wind (like biking at 10mph) flips it sideways, rendering it useless.

Why did you pick this product vs others?: Price and size Mirror quality: Mirror works great but fits really tight on my glasses, I switched to a bar mounted mirror for the bike. Keeping this in my toolbox for when I needed a mirror to view in a tight spot.

I lost my last rear view helmet mirror but the sellers of the one I like are gouging us at just under $20 USD and I reject price gouging so I bought one of these cheaper ones which look nice online. Problem: The long arm and the because the mirror has a plastic backing/frame which increases the overall weight of the mirror making it jiggle while you ride and threats you need to see are not visible to you. This particular design is easily adjusted left, right, up down and the metal seems good and resilient to bending but it's unusable to me because of the constant jiggling that makes it dangerous. I would strongly advise against this unless you ride 5 mph. I'm a competitive athlete and anything above that speed would put you in a dangerous situation of not being able to see threats (like cars and trucks) approaching your rear. Keep looking for a better item. There are others (which I won't name b/c of their price gouging) that just has a little mirror and not the heavy frame which is indeed better.

This bike mirror is a great alternative to the more expensive 'Take a Look' bike mirror which cost more than twice as much on Amazon. This mirror works just as good. The only thing is that the pivots are very loose. The mirror will easily go out of adjustment when inadvertently bumped. This happens often when you are removing or putting on your helmet. You inadvertently bump the mirror. It's not a big problem but you have to re-adjust your mirror often. Perhaps if I had another one to try, it wouldn't be so loose. Good clarity. Easy to attach to my glasses frame. Easy to use. Would buy again.

These helmet / hat / glasses mirrors are the only kind I use. I have tried many other types but the rear image is always very hard to spot. I have suggestions for improvements ... 1 ) make the part that clips on to hat / glasses more securable. 2) make the mirror swivel with more friction so that it doesn't move while riding. Thank you . Inform me when this is implemented, I will order my next set of 3 .
