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

I spent a lot of time researching bike mirrors, determined to buy the best, at a reasonable cost. Three (3) things were important. 1.) Good visibility, which translates to safe operation of my bike. I wanted a clear image with little to no distortion or excessive vibration. This mirror uses HD Glass, which produces a distortion free image.2.) Ease of mounting. For most applications, this mirror requires cutting a hole in the end of your handlebar grip, which takes a few minutes per side. Mounting the mirror is accomplished using a hex key (supplied by the manufacturer) that expands a mounting stem inside your handlebar. After mounting, it's solid and produces little to no vibration. 3.) Reasonable Cost. It cost less than $20.00 for a pair of mirrors. This is an unbeatable value.
