Review on BriskMore Bike Mirrors - Set Of 2, Bar End Rearview Mirror For Bicycles With HD Glass Convex Lens, Enhanced Safety For Cycling by Jason Peterson

These mirrors took less than a minute to install at the ends of my handlebars on my Boogie eBike. I used the allen wrench included and they screwed right in and stayed put through some very bumpy rides. It's so nice to be able to have these mirrors that don't move around (like the previous mirror I had installed on the handlebar itself). Others have said these inhibited their movement on the handlebar grips but I didn't notice any issues and didn't hit these with my hands at all. Now I feel very confident riding around in the streets. Big value for the price!
