Review on 🚗 Utopicar Car Accessories - 2.5" Blind Spot Mirrors, Enhanced Size and Traditional Shape for Expanse Blindspot View. Automotive Rear View Door Mirrors with Fixed or Adjustable Stick-on Mounting (2pack) by Steven Brouillard

I ordered blind spot mirrors and they were well packaged. They have an adhesive on the back so you can apply them directly to your car mirror, or you can place them on a small ledge which gives you more flexibility in fitting. I decided to place them directly on the car mirror. I washed the car mirrors thoroughly, placed the blind spot mirrors in place and pressed them down for about a minute. They worked great for a week. The driver's side blind spot mirror flew out, fell to the ground and broke. Adhesive aside, they work great and provide good visibility where you need it most when driving in city traffic.
