After a dozen years, I finally bought a new car. I had a fixed blind spot mirror on my old minivan, and it worked very well.For my new car, I did some research and bought these adjustable Utopicar mirrors. They are even better than the ones I had on my previous car. Compared to my old blind spot mirrors, they are much wider, have more of a "curve" for a wider field of view, and seem to provide some magnification. The icing on the cake is that they are ADJUSTABLE! The ball and socket swivel is GENIUS! A very logical and needed improvement to fixed blind spot mirrors. I wonder why someone didn't do this many years ago.3M is known to make excellent adhesives, so it should stick to the mirror for years, like my old mirrors. I can't yet speak to how "stable" they will be as far as the ball and socket yet, but it is pretty tight. If it does move, it should take 15 seconds to set back to where it needs to be.Because my new car also has a blind spot warning light on the outside top corner of the mirrors where the recommended placement is, I mounted them on the inside top. They work fine there. While the warning light is "nice", i really like being able to see exactly where the cars are.Think of this mirror as a "gauge", compared to only having what we used to call an "idiot light". Between this mirror and the blind spot warning light that the car came with, you pretty much have your blind spot "covered" and GONE.
