Verivue 2.5-Inch Fan-Shaped Blind Spot Mirrors for Cars, Universal Fit, HD Convex Wide Angle, Stick-On Frameless Side Mirror Blindspot, Adjustable Design Blind Spot Mirrors 2-Pack

Quality is good. It is adjustable. When I ride my motorcycle on the highway, I could clearly see the vehicles in my blind spot. $11 for safety is very cheap.

so my bestie hooked me up to these circle mirrors. they make such a difference when i drive! i can see when im merging so much better & i feel 10x more comfortable & safer when i drive. also get an extended rear view mirror they are a great combo !installing is also super fricken easy! my side mirrors have a weird shape but it works for all cars ! rain or shine, the adhesive on them is remarkable!

The blind spot on my car is ridiculous, so bought the in hopes of getting better side views. These work beautifully. The blind spots are now visible, making it much safer. The should be standard on every car sold.

perfect for my older car with small mirrors

I put these on just about everything. Adjusted properly they let you completely see your blind spots and a wide view of the road.

I installed these on a 2011 toyota 4 runner. I did not use the mounting bracket because I did not want the mirror sticking out from the original mirror. I read reviews and knew these were concave and most likely would not fit flat on the original mirror. I used a gel type of super glue with the already installed circular back sticker to put on original mirror. I wanted to fill in the concave gap. It got a little messy and had to use a razor blade to remove some glue. Time will tel how long they last. It did let me see the blind spot. I gave it 3 stars not due to a bad product, but for me and my use they did not install as I hoped. Round ones might have worked better. If you want a mirror to install flat on the original mirror these do not so one has to alter the installation.

Have been using round mirrors of all sizes from 1" to 6" since the mid 80's on cars, vans, trucks large and small including box trucks. Thought I give this a try as the picture shows being able to see everything besides being sharper. The quality seems good and mirror is crystal clear. The distance between the base and mirror is too far so you can see the red 3M sticker / on the back of the mirror.The curvature is so small it will only focus on a small area as you pivot. Unlike round mirrors you get a very large area of view such as the ground, curb, basically a shot of a wide 360 view. This mirror can only focus on a small area. In the position where you can see part of your car for reference you are unable to see the blind spot. A vehicle can still be hidden between this and the regular mirror. Totally unsafe and unusable unless you direct it into the blind spot but in the position you don't get a picture for reference of any of surrounding areas.If you are use to the round mirror this will be a hazard to your driving due to it's limitations compared to a round one. Returning.
