The dimensions of the AUDEW are as follows: mirror length: 9.5 cm, with a width of 3.5 cm; the material of the ADUEW is made of ABS glass, with an HD glass-curved, ultrathin, slim design. The ingenious concave design helps the driver to efficiently forecast their surroundings when passing or changing lanes.

What We Like

  • There are two installation methods available (horizontal or vertical) and the AUDEW is also IP65 waterproof, rust-resistant and the glass will not haze; the driver can also be confident in the fact that there is guaranteed durability with waterproof adhesive, leaving no residue on the blind spot mirror or your original mirror.
  • Another plus to the AUDEW is that it can also be used as a rearview mirror so it is not just limited to a blind spot mirror for your side view.

What We Don’t Like

  • This rectangular blind spot mirror is not as convex as it needs to be so it is possible that it will just simply provide a reflection to the original mirror and not provide an accurate view of any cars that may be in your blind spot.

What We Like

  • There is certainly nothing fancy about these particular bubble small wide-angle rearview clips on blind spot mirrors but they are perfect for those who are not looking for anything spectacular.

What We Don’t Like

This particular blind spot mirror can almost be looked at as the cousin to the one reviewed above, just without the swivel option, and for a pack of two on Amazon (as a Prime member) will cost you about 8 bucks. It adheres fairly easily to your original mirror with no worries about the adhesive smudging the original mirror in any kind of way; it is definitely ordinary in appearance so you will not have to worry about it taking it away from the look of your car in any way.

What We Like

  • One of the pros about this particular mirror is that, as the driver, you do not need to worry about bezel getting in the way of adherence, just in case you have a small original mirror, not to mention it is incredibly priced.

What We Don’t Like

  • The piece of adhesive that comes with this mirror is relatively small in size, unfortunately, so it does provide a greater chance of the mirror falling off unless you are able to purchase additional adhesive separately.


Overall, the blind spot mirror is definitely a good investment, however, when purchasing be sure that you are getting the best mirror for your needs; some of these mirrors are not meant to be placed on vehicles such as motorcycles so be mindful of that before spending your money.

The last thing you may want to consider is if you would like an egg-shaped or circle-shaped blind spot mirror; in my opinion, I believe that both shapes work equally well but naturally it would depend on your preference and the type of vehicle that you have. Also, prior to the application of your blind spot mirror, be sure to clean your original side-view mirror with some kind of solution- rubbing alcohol works well.

Beyond that, happy shopping!
