Review on Enhance Vehicle Safety with Utopicar's Adjustable or Fixed Blind Spot Mirrors - Wide Angle Rear View Mirrors for Cars [Frameless Design] (2 pack) by Brad Davis

Thought I should try them on a new car I bought. Were cheap $3. Lap on my old car (same model). These new ones are not as visible as plain round ones. Big difference! I attached these mirrors using an adjustable bracket (very easy to do and they don't come off on their own) as attaching them with the 8 adhesive stickers provided felt like a cute Mickey Mouse to me. I would recommend buying 2" or 3" (depending on mirror size) round convex mirrors that attach flat with a 3m adhesive sticker.
