Review on Adjustable Square Mirrors For Blind Spot By Zone Tech - 2-Pack Premium Quality Stick-On Side Mirrors For Cars, Trucks, Motorcycles And Snowmobiles by Peter Nobles

I really like this blind spot mirror set - it's wider and rectangular which I prefer to the round ones. However, it is also convex so if you want to mount it WITHOUT the raised adjustable post included you have to use layers of the adhesive provided. Hopefully they won't blow off or come off due to rain and car washes over time. Fortunately it worked for me (for now), but I'd prefer they sell a different version made to apply directly to mirrors that are already adjustable (like mine).
