Question: The boom & mirror adjustment keeps moving when encountering bumps & light headwind. What is the best way to tighten up these rotating contact points ?
Document: I think I tried every helmet mounted mirror out there - blackburn, sunlight, 3rd eye non-pro, cycleaware and maybe even some hat I have forgotten. This one is far from perfect but is the best one available. The mirror is large and flat. The mounting system is flexible enough to adjust just the way I like. The problem is that it falls off. I fixed this by putting velcro on the helmet and the mount.
The mirror itself is great, with two ball-and-socket joints providing a great range of adjustment. Gravel did not jolt the mirror out of position permanently, although it definitely vibrated with the bumps. The mirror's reflective surface is resistant to scratches and gives a good, clear image.The adhesive did not stick well to the inside of my helmet. I am going to scrape off the 3M adhesive, try a superglue and, if all else fails, mount it with small screws.
Mirror holds steady over bumps, rough surfaces, and wind. The arm could be longer and length adjustable to aid in getting the line of sight perfected, but as long as I frame the mirror bottom/inside with the shoulder/ear, I can see behind me with minimal vertical adjustment. Mounting inside my Bell road helmet put the swivel post too close to my forehead and the the vent placement prevented an outside mount.
Riding on rough roads or pedaling hard (which makes my head bob around) emphasizes the problem.Pros:  Well made. Light weight. Doesn't easily come out of adjustment while riding, although is easily bumped out of position when I take the helmet off. Relatively large mirror area.Cons:  Have to re-adjust it every time I put the helmet on.
I have owned both the Cycle Aware Reflex  and the Third Eye Clip on,  and Third Eye Pro helmet mounted bicycle mirrors. The new Third Eye Pro is absolutely the best helmet mounted mirror I've used. The larger mirror on the Third Eye Pro is amazing. Excellent optical quality. Great adjustability. I found that the gooseneck adjustment of the Cycle Aware got very loose and would come out of adjustment all the time. THe Third eye has ball and socket joints that are much more adjustable and stable.
You want to make sure you get as flat a surface as possible to maximize the contact, however... where it is not a flat surface...4. ...You want to make sure you bend the device as much as possible to conform to the surface to make sure every part makes contact.One word of caution- I originally found better mounting surfaces INSIDE my helmet and tried that, but then a part of the mirror was up against my head, which I knew wouldn't work.
The product arrived as advertised and is of adequate quality and construction for the price. Adhesives provided with the product are not that great. I ended up using contact cement in order to attach the product to my helmet.
I have been using these mirrors for years . They are the best helmet mirror I have found. good product!
Piece of carp that keeps falling apart and the lens is blurry. I tossed this thing right into the garbage.
I love the way it works once mounted and wouldn't recommend anyone ride without one. I've recommended this mirror to several of my friends and they think its great.
