4 PCS Car Rear view Mirror Rainproof Film, Foseal Drive Safely in the Rain HD Clear Anti-Fog Nano Coating waterproof Films Anti-scratch Protector for SUV Car Mirrors Side Windows, Round (3.74"x3.74")

First day - when I installed this... it was amazing... I was so happy with the product... (It was raining and it helped me to see the big difference between this product on)Second day - It's strange it's no more preventing "raindrops" from accumulating on it.I contacted the seller and he confirmed that this needs clear water and clean cloth maintenance. After cleaning it .... it worked just fine.

Very bad product never bye it just waste of money yesterday was raining but I was even able to see any think I am very disappointed to the seller I don’t know how to return because I had place it

i have no clue what this thing is made of but it's pretty awesome!!! living here in texas and it's been raining a lot lately around rowlett and dallas area. put these things on the rear view mirror and it's been working like a charm! the only problem i have with these is that they are round. i should've bought the bigger squareish round ones so that it covers more of the mirror. overall, they get the job done and you won't be dissapointed.

These are pretty easy to install. Like putting a screen protector on your mirror. It hasn’t rained so I don’t know how well they work, but they do not get the morning mist on the mirror which is nice.

This rainproof film is proving to be better to have than not. It is useful in the mornings when my side mirrors fog up and also when it rains. And Fall is just the right time to put these on my side mirrors and on the outside of the windows. Each film comes protected on both sides and you peel side 1 to stick it on your mirror, and then peel side 2 once you have installed the film. The installation instructions are given and there is also a card with some kind of textured tape on one end that is used to scrape the water and air bubbles out.

Protect view. Great mirrors and easy to install. Like that they are adjustable. Cheap price and good quality

I purchased this one because I live in a City where it keeps raining a lot, and usually it gets difficult to view the cars that are behind. I even installed the blind spot cameras, but still when it rains the rear view mirrors gets full of fog.I guess this definitely helps you to view the blind spots. Overall, I like this very much.
