Review on POMFW Rearview Convex Side Mirrors for Cars SUV Truck Van - Stick on 3M Adhesive, HD Glass Frameless, Sway & Rotate Adjustable Wide Angle, 2 inch Rhombus - Set of 2pcs by Tom Goodlow

Works well on the outside bottom corners of my 18 Silverado mirrors so I can see the rear tires and as I approach curbs, lines, etc. They are larger than I would like, but I couldn't. I couldn't find a slightly smaller size that I was sure would work for my purpose. However, considering that the rear tires limit visibility in blind spots, that doesn't bother me too much. I put black tape on the back of the mirror to darken the back. It's a little less distracting than the white lettering on the included self-adhesive backing.
