A really good mirror. Takes a bit of getting used to avoiding my left leg when off the bike walking or whatever.
Good view when riding.
Downside: Very poor screwhead on the pivot bolt. Easy to damage, soft metal, shallow slot.
Suggestion: I wanted to make it more secure, but not permanent. I disassembled the pivot, put rubber cement on the faces, reassembled, adjusted, let it dry. Hasn't moved since even when bumped. And if I need to change it, the rubber cement will give.
I placed the mirror on the left bar end of my drop bars. The pack offers two sizes of rubber plug that fit inside the bar. These are contracted and thereby tightened with a screw that attaches the mirror assembly. The large plug was too big and the small was too small for my bike, a Marin with what looks like a standard bar to me. Eventually, I banged the big plug in most of the way with a mallet and was able to tighten it down. It's been very secure. The mirror optics are fine and it stays steady once positioned. It's a small mirror, so If I shift my position significantly I have to adjust the mirror. That's reasonably easy to do while riding.
I've purchased and installed several Third Eye Bar End Mirrors in the past, but these were installed on a tadpole trike and not intended to be used in the bar ends. I added a small piece of angle aluminum to each fender mount on the tadpole, took the mirror base apart and removed the bar end pieces, replaced the bolt with a shorter one with a Nylock nut, and attached the adjustable mirror head to the angle aluminum so that the mirrors are mounted directly over the front fenders. Worked out great. The mirrors look good and are out of the way. And of course they provide excellent rear vision which is really needed on a tadpole trike because it's very difficult to turn and look back in the form fitting seat.
I was most impressed with how little this mirror vibrates while riding. I'm not an engineer, but I think that's because there's almost no stem. Screwed tightly into handlebars, just like they said. Mine came with three different sized rubber expander sleeves, but not a lot of instructions, so it took a little experimenting to get it right.
I purchased this mirror as an upgrade from an older bar end mirror. The method of mounting makes it very secure and the adjustable tighten allows it to stay where it is aimed. This is a must if you're riding in traffic.
This mirror gives a great view of what's behind you. I regularly ride on the shoulder of two-lane highways and in my mid-60's I've lost some comfort level when looking back, so I bought this mirror. I do wish it fastened more securely. I check it before every ride. 200+ miles though and no problems.
I ride a lot in Atlanta traffic. I've pondered this mirror for years, and now I have no idea why I was suspicious. I guess because I never saw Miguel Indurain use one. This mirror weighs nothing, costs little, installs in seconds, and does not vibrate, so you can scan the road behind you with a quick glance. It takes about two seconds to appreciate it. It is especially nice because there are now many electric cars in the city.
So it works, that's good, but it's far from ideal. It needs to be micro-adjusted to really give you the view you need, but it's not easy to adjust and once adjusted it doesn't want to stay in place.
Don't let the price for you this is a top quality glass mirror that is easy to install keeps it's setting and can be adjusted at just the right angle for you to see behind you without having to lift your head
Installed and went for a short ride to test it out. Could easily see traffic approaching from the rear; much better than my small helmet mounted mirror. Safety is becoming a bigger issue as it seems cyclists are having to avoid increasing numbers of inattentive/distracted drivers. This tool may save my life one day.
It never occurred to me to have a mirror before I started riding to work 2-3 a week. Now, I can't see how I ever got by without it. I just adjust it however slightly is necessary to get a good rearside view. This allows me to know when vehicles are coming up from behind, but the real difference I've found is when I've got to execute left turns or merge to a left turn lane. One little awkward bit is that when I'm in the drops, the mirror is in the way of my wrist. But that is a minor inconvenience when compared to the overall benefits of having a clear view of what's behind at all times without craning my head around and losing visibility of what's ahead at the same time.
I use this mirror on my road bike. It took me a while to get it adjusted properly, but once I did it functions well. It's not obtrusive and remains steady even when riding on bumpy terrain.
For the price it is a real good deal. I did have to shim it to make it fit in the dropbars I have . It works good I can see vehicles coming up from behind me better than I did with the other cheap mirror I had. Does take a little getting use to looking down but I can see what is behind me. Good price Good product.
I bought this to try it out. I'm using this mirror at the end of the tube of a drop handlebar. I was able to find a position that is functional, but additional articulation would make this product more useful. Possibly it works better on other style handlebars; I haven't tried that yet. On another bike with a drop handlebar, I have an old-style Mirrycle through which the brake cable passes. I prefer the Mirrycle mirror.
I won't ride out on the streets without a mirror and this mirror (3rd Eye Barend Mirror) works great! I have it on all of my bikes too.
In today's hi tech world of cell phones, texting, and GPS, drivers are more distracted than we know. And you never know what the driver will do with that technology as they are approaching from the rear. You absolutely have to be able to see what is going on behind you as you bicycle. This mirror is the tops. Clear, scratch proof glass with a wide enough angle, but not yet to wide, as to make vehicles appear too distant. Solid mounting inside end of handlebar assures no vibration at all. Get this mirror!!
