Hestya 2 Pcs Bike Mirror 360 Degree Adjustable Safe Rotatable Handlebar Mirror Bicycle Accessories Shockproof Acrylic Convex for Mountain Road Bike

I've used similar mirrors on bikes before, which were even smaller than these ones. I find the size perfectly adequate to spot cars coming from behind. I normally mount these mirrors on the vertical frame member below the handlebars. This way I can glance backwards between my legs, as it were. Yes, they are not the strongest around - but they are a cheap, smallish plastic mirrors, which do their job.

cheap plastic, very small can hardly see out of them, spins round, too loose,

These are very small, but I use them on my mobility walker, as I was always worried about getting in somebody’s way. Ideal for my needs, but a bit small for most things, also, the mirrors have a habit of moving, so need repositioning. Still good for what they are

Absolutely brilliant mirrors for my cycle.Rubber strap on them, so easy to install the mirrors. I attached mine to the end of the handle bars.The mirrors are small, so I was apprehensive that there would not be enough of a rear view for my safety. Thankfully not the case, and they are very good in terms of field of view.Also being small, and with a swivel and fold mechanism, means they are easy to bring the bike indoors without scraping the indoor walls. And also means the mirrors don't stick out on the bike, so they have a good aesthetic design. Very low price, good value.

As a car driver I like to know what is behind me.The mirrors are easy to fit but you need the space on your handlebars or the right type of handles to ensure they are positioned far enough to the tips to get a good view. They hold their position with minimal shake.

Perfect. Good value.

I'm a bit disappointed the mirrors are too small that you cant see anything behind you what a waste of money

Absolutely love these mirrors,easy to fit,and when adjusted,stay in pisition well,very happy,and would highly recommend,to all cyclists.
