Third Eye Pro Helmet Bicycle Mirror

Other reviewers have praised this product: lightweight, little vibration, wide field of view. I'll just try to add a little bit to the already extensive advice on how to mount it.I have a Bell helmet with vent holes and some channels molded on the outside for artistic effect. The mounting piece is flexible enough to accommodate some irregularities, so don't worry too much about minor bumps and ridges. I didn't see any way to mount it inside my helmet, but your helmet may be different.The plastic arm holding the mirror needs to be tilted down about 20 degrees to bring the mirror in line with your eyes. Line up the arm perpendicular with the mounting plate, put the helmet on your head, and slide the mounting plate forward and back on your helmet so the mirror is 3 to 3 1/2 inches in front of your eyes. Closer to your eyes gives you a wider field of view in the mirror but obscures more of your forward vision. I prefer closer. Then rotate the mounting plate so the mirror is directly in line with your eyes or a little higher. You want to be able to move the arm up or down about 30 degrees from its centered position. Hold the plate in place while you take off the helmet. Then outline the location with a pencil.I used a single-edged razor blade to pick up the adhesive strip from the white paper backing to avoid getting the oil from my fingers on it. Clean the mounting location with alcohol. Place the adhesive strip on the outline you've drawn and press it in place. Use the razor blade to pick away at the protective brown paper on top and peel it off. It's not easy, but the adhesive is permanent and the strip itself won't lift off, but the paper will.Clean the mounting plate with alcohol, put it on the exposed adhesive, press it in place, and you're done.Here're the manufacture's own instructions:--------------------MOUNTING DIRECTIONSNote: Temporarily tape (masking tape) the mirror mounting pad to the helmet (It fits nicely on the inside of most helmets) until you are sure of the position, the adhesive is not forgiving.Place pad on smooth, clean and fairly-flat area of the helmet. (on Foam helmets slight ridges or irregularities may be carefully sanded or filled flat to make the pad adapt better).For optimum results, the mirror should be about 3 1/2" from your eyeball. Don't worry about focusing that close, your eye actually focuses on the Objects behind you.Position the pad and adjust the inner ball joint so you can see the mirror in the upper outer corner of your eyeglasses or your field of vision.Aim the mirror, using the front ball join so you can just see the outer edge of your ear.Mold the mounting pad with your fingers to fit the shape of the helmet. Peel the adhesive and brown paper off the (white) backing paper. Stick the adhesive material to the side of mounting padthat fits against your helmet, flat side for outside mount, the side with post for inside mount, peel off brown paper. Press the pad to place.The front ball is set at an angle to the shaft. if you attached the mirror on the right side of your helmet rotate the shaft so the arrow points OUT away from the helmet.If your helmet has a Iycra cover; mount the pad to the helmet then disassemble the rear ball joint. Put the cover on. With a hot instrument melt a small hole in the Iycra that just lets the ball stickout and reassemble the mirror.Do not use adhesives that have solvents that could damage your helmet or mirror.

The mirror I've preferred for several years apparently no longer exists so this was the closest I could find and it's working well so far. I'd prefer a mount that doesn't cover such a large area and ended up putting it on the outside of the helmet because it just felt like it would be too uncomfortable on the inside. It seems to be stable so far.

I've used helmet mirrors for 40+ years. Until six weeks ago I'd never been hit by a car, and I credited my helmet mirrors. Then a pickup made a right turn from the left lane cutting across heavy traffic and hit me in the bike lane. Luckily I wasn't badly hurt.Life On Bicycle 360 Degree Adjustable Rearview Bicycle Helmet Mirror: This mirror is tiny. It's on a long, long metal arm. It mounts with velcro (the velcro sticks to the inside of your helmet). The result is a small view of the traffic behind you. The view is shaky as the velcro doesn't hold the arm firmly and the long arm multiples vibrations. The mirror catches on my screen door, on my fairing, etc. 3 stars. This mirror is in the picture of a helmet with two mirrors.EVT Safe Zone Bicycle Helmet Mirror: This mirror is huge. And it's expensive. It mounted onto a standard helmet (the kind with lots of vents) with cable ties. It works, but I hated it. It's too big and in the way. 4 stars. No picture.Third Eye Round Helmet Mirror for Hard Shell Helmets: This is the best mirror...if you have a hard shell helmet. It mounts to the outside of your helmet, not to the inside. These keeps the mount well away from your head. The mount is solid, and you can unscrew it to move or remove the mirror. The short arm doesn't amplify vibrations. You get a big, steady view of traffic. The problem is that hard shell helmets are all but gone. Bell might have some skateboard helmets with hard shells. 5 stars. This is the picture with the white helmet.Third Eye Pro Helmet Bicycle Mirror: This is the best mirror for modern helmets. It has a short, solid arm. The arm sticks to the inside of your helmet. The mount is close to your head and can put pressure on your temple if not mounted perfectly. The sticky tape lost its stickiness on one helmet so I had to secure it with a cable tie. You get a big, steady view of traffic. 4 stars. This mirror is in the picture of a helmet with two mirrors and in the picture with the yellow helmet.Why don't helmet manufacturers include a mounting plate for a mirror? My guess is that they're scared of lawsuits. Some lawyer told them (I'm guessing) that a cyclist could crash and get an eye injury and sue the helmet manufacturer if they had a feature that no other helmet has. So helmet manufacturers don't like to innovate.

This review is not a negative review about the "PRO THIRD EYE MIRROR" or the company.My feedback is about the overall design of the mirror itself. The idea is good, you're riding your bike on a trail or road and you want to see if there is a car or another rider coming up behind you. You think to yourself a mirror would do the trick.Ok, you mount a mirror to your helmet, that takes a little time and temporary tape until you decide where you want/need to locate it on your helmet for the best placement. You start to ride, and initially you have to stop a couple/few times to position the mirror until you get it in the ride placement. Once that's done, the vibrations from the bike will over time, undo your positioning of the mirror, so you will have to fine tune it periodically. Also, peripheral vision and double vision might come into play depending on your placement and positioning of the mirror. If all goes well and you've got the mirror and its placement dialed in, along comes a fly/bug and you swish it away with your hand and accidently hit the mirror.....now you have to stop and reposition it all over again. All and all, I've tried 2 different "attach to your helmet/glasses" type mirrors, I've opted for the mirror that attaches to my handlebars, which is a marked improvement to the helmet/glasses mirror option.

... ist nur den richtigen Platz zu finden. Danach ist es eine Frage der Gewöhnung. Ich bin eine Gleitsichtbrille gewohnt, da ist das Schauen etwas schwierig. Aber besser als nichts sehen ist es allemal. (4 Sterne)Nachtrag: Bin ein paar Tage ohne Spiegel gefahren. Als ich den Spiegel wieder aufstecken wollte, fehlte ein Teil in der "Pfanne" des Kugelgelenks. Da so etwas nicht herausfallen darf – besonders nicht bei dem Preis – und der Spiegel nun völlig nutzlos ist, ziehe ich drei Sterne ab. (Für alle, die den Spiegel für immer und ewig am Helm lassen wollen, bleibt es bei vier Sternen.)
