Bike Mirror，JOOKKI Rear View Bicycle Helmet Mirror，360 Degree Adjustable Wrist Mirror for Cycling

Daytime=small mirror dedicated to immediate lane left or right of biker. Images (Auto) visually lost with background road and skyline AND can not see second lane (no expanded view unless you turn mirror=difficult while riding). EVENING= better view thanks to auto & biker head lights. CAN NOT recommend this product, BUYER- get a stable wider handle bar mirror.

Not very useful. Have to take off eyes off road to lift hand to face.

I have not used this while riding in the street yet.Pros:I like the 360 rotation ability.You can use this for various things like when you want to know who's behind you (ATM, night walk, etc.)Con: It's difficult to fit and position properly with one hand. I wish the band was made differently to fit easier.

The image is very small due to the strong curve of the mirror and objects are much closer than they seem. Takes some getting used to but works and is necessary where you are storing a bike in a cramped bike rack tnat would ruin a handlebar mounted mirror.

Well made. Pretty good quality. Not good for distance. Mirror a bit small, good for right next to you or right behind you.

I recently got a new bike that had handlebars unsuitable for mounting a mirror, a hybrid bike with up turned handlebar ends. I tried helmet mounted mirror and found it very small, very had to focus, I am far sighted, and spent more time trying to use it then looking at where I was going. So I tried this wrist style mirror and am never going back to other style. The mirror is light weight and the cloth/Velcro band is easy to adjust, and not sweaty at all which was a worry. Depending on where on arm you place it, about half the mirror is obscured by your body while biking, but other half is good view of what is behind. A simple move of the wrist and can get all of mirror obscured when want to see more. Other nice feature is that it is portable and when use other bike can take this with you like I did this past summer when went on a bike tour in other country.

This is a well-made product. I was excited to see it offered, because I rely heavily on the mirror I have installed into the end of my left handlebar, and wanted one I could carry with me when I rent bikes sometimes. But there is a big difference between a mirror on your wrist and one protruding from your handlebar. The latter gives a very broad field of vision, while any mirror worn on your wrist cannot accomplish this. It's still better than no mirror at all, but it doesn't accomplish much beyond showing you the reflected image of your shoulder.

This mirror does exactly what it is supposed to do... if you find that sweet spot on your arm! After trying multiple angles and locations along the arm, I have found that "just below the elbow" is the sweet spot for me. Once I've got the correct angle and position dialed in, this baby has become an indispensable item for my commutes, workouts, and tours. Just be a little openminded on where the sweet spot is and I promise you that you will learn to love and rely on this rearview mirror for all of your cycling needs. In fact, after several of my riding buddies/buddetts saw this innovation, they asked me to hook them up, to which I happily complied... to date, 4 of my group members sport this mirror because of my willingness to try it out. Just remember, it is capable of accommodating many sections of your arm, don't limit yourself to the wrist and lose the potential possibilities of this ingenious safety device for cyclist!!
