Not such a great bike mirror

Returned it because the velcro straps don't hold the mirror on the handlebar of the bike.

Mirror installed easily. The concept of such a small, non magnified mirror on bar end is flawed. Difficult to use. In fact, one has to stare down at the mirror too see anything. Distracts from keeping eyes on the road. Mirror piece fell off after 2 months.

UPDATE: After only several months of use, one of the mirrors fell off. I use my bike on surface streets only and ride abouit 30 miles a week.

I thought it was to pricey, not sure if a handlebar would have been better for trail bike, I might return it, Im sure its good if you're looking for a helmet mirror

The surface of these so called mirrors are inadequate. And for one it was not set right in the frame. Do not recommend these "Total View"!

Previously purchased the largest Hafny bar end mirror for a mountain bike.  I really like it.  But with my aging eyes, considered a larger mirror on my road bike.  Well this mirror is larger and cheaper, so I purchased it. Minus stars for:  It's poorly made or poorly designed...hard to believe it's manufactured in the U.S.A.  I had to use an adjustable wrench and a ratchet screwdriver that has different size bits to finally get it together.  Forget about using the little tool (hex wrench) that is included unless you have the grip strength of Wonder Woman.  It's states in the instructions that the cap screw fit into the brass insert is extremely tight.  Boy, they aren't kidding.  In other words...tough to tighten it down.  You have to do this "twice".  The whole time I was gripping and turning, it was making this horrible noise like it was going to snap at any moment.  It also states in the instructions: "Don't worry about breaking any of the parts."  I wasn't totally convinced, but it didn't break.  I had previously given it 2 stars but thanks to another reviewer, I finally figured out how to install on my road bike so that it doesn't get in the way of the drop down bars.  Box shows the mirror is for hybrid, commuter, recumbent and road bikes.

I have my mirror mounted on a road bicycle with dropped handlebars. When I'm on the brake hoods, or the top of the bars, my arm blocks my view of this mirror. So I also use an eyeglass mirror,&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Bike-Peddler-Take-A-Look-Cycling-Eyeglass-Mirror/dp/B001VTQNVO/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Bike Peddler Take A Look Cycling Eyeglass Mirror</a>. But when I'm in a tuck whipping down a hill, I can't see behind me via the eyeglass mirror. (I'm in the way.) So I bought this mirror and have it adjusted so that I can see cars approaching, or receding in the distance as I pick up speed.

Being on the handlebars, it does vibrate more than the eyeglass mirror so while the view is fine, it's not as good as the eyeglass view. Still for the same reason my car has 3 mirrors, having two on a bicycle really helps for riding in traffic.

Unlike the other reviewers, I've had no trouble mounting this mirror. I've been using it for two years and haven't had any problems with it. I'm not quite a daily commuter but I ride a lot. I used one of the thinner rubber inserts to get the sizing right but it was no trouble at all.

I park my bike along with a zillion other bikes and the mirror gets bumped every day. With the hinged mount, it's no trouble to re-align it and off I go.

So if you don't have any mirror, the eyeglass one is preferred, but if you commute in traffic, this one will help.

The mirror I got from the bike shop was useless unless I wanted to see my shoulder. This mirror will rotate at the holder on the bike and at the mirror itself. It is a convex mirror as well.  With this mirror I can easily see the road behind me. Fix well on my standard bike. Will be getting another for my wife.

No fun house mirror here, only drawback is that the mirror itself is set in the frame cheaply, I screwed two thin cleats across the back and its fine, don't always expect perfection and be willing to put a little work in and you will be happy

The Mirrycle system makes it easy to position and adjust the mirror. It attaches to the outside of the handlebars and if you position the mirror to extend beyond the handlebars as most people do, it will likely break if your bike takes a tumble on that side. I wonder if it would be possible to make it less fragile without sacrificing image quality or increasing price enormously.

It comes close to being great, but leaves room for improvement.  The primary annoyance is the riveted joint under the boot where the arm is connected to the bike mount.  It rotates just like the OEM, and it also stops at an indexed position.  But the position it stops at does not provide a firm engagement.  This looseness allows the mirror to vibrate/shake when the bike is ridden.  The second feature that needs improvement is the fit of the boot to the flange that is mounted to the bike.  The boot is loose around the flange instead of the factory quality boot that fits snug and is held in place by the flange.  Now for the OK parts.  The boot itself has a glossy texture which is different than the original.  That is not a big issue, however for my application just one mirror needed replacement so that means that the two sides don't match each other.  The reflective mirror is fine and it fits into the housing without gaps.  The holes in the flange align with the holes in the bike so mounting isn't an issue.

Since I really only needed one mirror, I bought this&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Bikemaster-Replacement-Mirror-Left-Black-Suzuki-Katana-98-06/dp/B0036GBGXA/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Bikemaster Replacement Mirror Left Black Suzuki Katana 98-06</a>&nbsp;afterwards instead of settling for these mirrors and was extremely satisfied.  The cost is higher, but peace of mind that I'll see a stable image behind me is worth it.

This mirror is dangerous. In order to see in the mirror, I have to look almost straight down at the ground and position my leg just right. This takes 1-2 seconds and is a serious distraction from looking ahead. I replaced this mirror with the Mirrycle MTB Bar End Mountain Bicycle Mirror and that product is far superior.

These might be perfect for attaching to your computer monitor but are not that great for blind spots.  The mirror isn't curved enough for my needs and the curve it does have isn't constant.

The mirrors are barely visible from a riding position on the hoods.  Which is where most cyclists spend most of their time.  The fitting into the handlebar plug is loose and so the mirrors vibrate making them useless.  You cant see anything because its all blurred.
This is one of the worst purchases Ive ever made on Amazon.

Mirrors are nice, but they shake too much on my Buell. Not the mirrors fault, would most likely work on another bike.

OK, but not great, the bracket sticks out too far from handle bars, so I rigged without the bracket.

The primary advantages of this mirror are that it does not block the standard mirror, and it is
less convex. Disadvantage rust.

I tested it as an alternative to a 2-1/2 inch round convex aux mirror mounted at the upper left corner of my side view mirror, or a small rectangular adjustable mirror in the upper right corner. I have had many miles of driving experience with these types, but have never been nappy with their blind spot coverage. (Buying a new vehicle is not an option) Each of these provided a wider angle of coverage, but a more distorted, smaller view that included areas already covered by the 3 standard mirrors, which are positioned for minimum overlap and don't cover the body of my SUV.

 This mirrlor easy to mount however no instructions are provided.  The bracket is of heavy gauge steel  screwed  into the  bottom  of  the  case.  It may not fit some standard mirror housings that have a close fit between mirror housing and moving mirror.  The case is available in 2 finishes black and fake chrome plated. The unit I received had a prominent mold parting mark on the top of its case.

It's not clear where that small piece of foam tape is supposed to be used. After dry fitting mirror to the  driver side mirror of my Honda SUV, I discovered that the steel bracket is of sufficient thickness that it rubs on the moving primary mirror when held in place, and the screws were not quite long enough to touch the mirror housing.

I placed the foam tape pad under the screw tips to prevent scratching. Altnougn the mirror housing is thick on this SUV, with the screws completely tightened, the mirror was still wobbly. I replaced the foam tape with a thicker piece of scrap rubber, which worked, although the motorised mirror bindld against the bracket it if is angled to the top of travel. This should not be a problem for most drivers watching their blind spot , not the sky.

I am tall, so I drive with my seat pushed back and slightly reclined.  I tried mounting the WA mirror on each end of the top of the main mirror.

Mounted inboard, with the WA adjusted as far outward as it could go, 1/3 of the reflected view was of the side of my vehicle, which is useless information. Blind spot coverage was slight. Mounted toward the outer end, the blindspot coveage was better, but didn't show a compact car to my left whose windscreen was level with my dear wheel until I angled the mirror downward. With this adjustment, rear coverage starts about 3 car lengths rearward and is disorienting to me. My shorter spouse has a much better view without adjusting the WA mirror.

Although the photos show this aux mirror mounted on top of the side mirror,  for tall driver on a vehicle with a side mirror that is at a height taller than the roofline of a midsize car, it works better mounted beneath the side mirror. This may be impractical on vvehicles with low hung side mirtors. A very short driver might not be able to see the WA mirror in that position, unless using an adjustable height seat or a booster.

Conclusion: this is a compromise worth trying because of the low cost. The limited miror back ball swivel angle combined with mirror housings that angle inward toward the vehicle and the small bracket prevent it from being mounted in a good coverage angle.

 If the fixed mounting bracket had one slot to allow the body to be angled further outward relative to the bracket, and then tighened in place, it could be a much more useful product.

Followup: After a few months the steel mounting bracket started rusting and staining the housing of the main mirror.

Provided bolt/screw  was too short to assemble the mirror. I had to go to hardware store for longer 5 mm bolt/screw. Scratched/smudged when received, in just two places. Mirror did not pivot enough to allow for a horizontal positioning of the mirror. I like that the mirror folds to narrow the bikes width when storing the bicycle. The image in the side view mirror does not suffer from some of the small imaging via the convex design of the mirror like most. Easy to see rear traffic at a good distance. Much larger than my past mirrors and I really enjoy that aspect of this mirror. Really, it is a good mirror and I like most features. If you have a true straight T-Bar handlebar it will work fine. My T-Bar is not a true tee it is slightly bent.
