2pcs Fan-Shape Blind Spot Mirror for Car, Car Blind Spot Frameless Convex HD Glass BlindSpot Mirrors Side Mirror, Rear View Mirror with Wide Angle Adjustable Stick for Cars

These are better than I had hoped for. You have the option to install with or without the swivel base which is what I wanted. They are very thin and barley stick out above the rear view mirror, without the base. My car had terrible blind spots and now seems so much safer.

I love the fan shape mirrors, they perfectly go with the curves of the mirror, highly recommend

Don’t try to put these on without the bases. I am so glad I didn’t, because it’s clear they would have never worked without them, just showing another view of what my side mirrors already show.They protrude quite a bit with the adjustable bases stuck on, but are still probably going to be fine within my car’s existing mirror shrouds—we’ll see. They’ve been very difficult to aim correctly, particularly the one on the right side.The correct way to aim a blind spot mirror is so you never lose track of a vehicle or bicycle as it moves from behind you to visible in your front side windows; these are tiny and don’t have much curvature to them, so many times, I end up largely seeing the same thing my side mirrors already show. Or they’re aimed too high or too low. They’re of course not adjustable while driving, so I need to tweak them when I next park and try again next time.I’m hoping they provide that critical extra little bit of extra visibility, but I’m torn on whether they’re worth the frustration—particularly if they end up getting knocked out of whack at some point. Longer-term, we’ll see.

There's nothing like trying to get into the left lane on the highway and there's another vehicle already there, that you hadn't seen. This mirror, which is easily applied, provides a wide viewing angle covering the otherwise blind spot that your side mirror misses.

I have used blind spot mirrors on all of my vehicles for years. Even though my current vehicle has Blind Spot Monitoring, it is only activated when using the turn signals. I like these as an additional safety feature.I do not use the adjustable mount, just the mirror itself [nice to have the option though]. I placed them in the lower outer corners of my outside mirrors. They really do add another dimension to the mirror's available viewing area. The mirror material seems to be of pretty good quality without distortion.They have worked well and seem to be standing up to the automated car wash too. Overall, this is a good product at a good price.

These are great!The "fan" shaped little mirrors can fit the contour of whatever your vehicle's mirror edge shape or curve.There's a STRONG adhesive backing on the mirror itself--You can:1. Mount the mirror directly as in my photos. or2. Included are stand-offs so you can mount the mirrors with a "neck" that can be adjusted for longer trailers and what-not.The field-of-view is greatly improved with these installed on my Dodge Journey.To be honest, I will probably never go without these on any vehicle. It's a no-brainer and SO SAFE.My only long-term concern will be how the adhesive holds during extreme summer and winter weather--as well with my heated mirrors.These really improve your blindspots! Should be included on all vehicles already!

Very helpful mirrors to help with blind spots. They seem to stick very well so far.

These mirrors work really well at covering the blind spots in the side mirrors on your car. The tape adheres really well. If I were doing it again, I would just stick the mirror directly to the car and not bother with the rotatable part. I'm not sure it if will be a problem with the mirror sticking out a bit with the snow and ice in the winter. Time will tell.
