Very helpful for riding in bikelane when there is traffic around. Also helpful when approaching intersections.
Size and view it provides does take a little getting used to; because of the size and position.
I use this on my road bike. I have tried some other mirrors which don't work well or get in the way of the brake levers. Adjustable at several points. Must be careful when laying bike against wall, etc, which may move it out of adjustment.
I've used this mirror on my T-bar commuter and both road bikes. It works great on drop handlebars, and doesn't flop all over the place like helmet or glasses mounted mirrors; I've tried them all over my decades in cycling. This is the best of the best.
I have one of these on several bikes from my Salsa Marrakesh flatbar to my Trek 790. Once you get it adjusted properly and tighten the screws sufficiently, it's very stable and much more clear than a metal mirror. May stick out too far for riding trails but I ride mostly roads and open trails. You do have to be in riding position to get it properly adjusted and you also have to tighten all screws sufficiently to ensure it doesn't move but I've had mine for several years and have never had to readjust except when I changed my handlebars.
My eyes aren't as good as they used to be so I appreciate a larger, glass mirror and this fills the bill. The bar end is easy to mount and I like its adjustability and ease of moving when storing the bike. The handlebar models of this mirror work just as well, except their mounting method can be tricky. Good mirrors, easy to see with, good value.
If you like a mirror that constantly have to adjust to even half way see, then this is the mirror for you.. Rode with it a half mile, threw it in the woods... more crap for the public to buy...
Mirrycle mirrors easily connect to all my models of trikes they are solid and adjustable for a good view of area behind, as the instructions for assembly say you can tighten them considerably without risk of breaking they can fold out of the way for storing or close quarters and can reset and hold position very well I plan to continue buying these for all my Trikes
