SummitRV-16P Circular Blind Spot Mirror (pack of two mirrors) Convex Mirror, Stick On Blindspot Mirror

Work as expected, easy to install, of course these don't fully cover the blindspots, but I'm sure most competent driver's will know this! Great value for money, I've always ordered this brand in the past.

Good product

I have a set of these on all my vehicles. They don't look out of place and are extremely useful.Easy to fit, great size and it's amazing the extra view you get additionally on you wing mirrors.

If your car is not already fitted with convexed outside-corner mirrors, this can be an extremely helpful purchase.With these mirrors you get a much wider, fish-eyed view from the mirror, and allows you to briefly look and see any traffic usually obscured by blind spots. Instead of constantly checking your blind spot, you can use these to judge if you need to check. This doesn't fully eliminate the need to check blind spots as they're distorted, but you can see if anything might be there, reducing the amount of checks you might need. Especially useful for lane switching on motorways.These also have an additional very useful feature. When in a lighted area, if you placed them appropriately you can see parking bay lines when parking. This is wonderful if you have difficulty lining up your car within parking bays, and helps you become more confident at your general parking abilities. You can also see how close you are to the curb if roadside parking.The one downside I find is that it doesn't take a lot for these to mist up and become useless. If you don't have a sponge handy to wipe down your mirrors, you'll find they frost up a lot, and will frost up more easily than your mirrors. If you can keep them clean, you'll have no issue however. Frosting also seems to be temporary, and mine always return to a normal state.

Installed on gate posts to see pavement at edge of drive, which enables me to see if there's someone coming before they get a fright/ squashed. Would work equally well on truck mirrors as intended. Adherance to smooth surfaces is excellent and they are still in good condition one year on from purchase.

I bought these for use on a motorcycle. Decent enough quality. Cheap as chips. A safert device for next to nothing.

Having previously tried the adjustable equivalent, I like this one which sticks flat on the mirror and gives an excellent field of view. Durability is yet to be established but they're cheap enough

Had one that did not stick to the wing mirror, but the other one was fine but was very easy to install. I use this to reverse park into the bays.
