What is Reddit's opinion of Fit System 3891 Deluxe Universal Clip-on Trailer Towing Mirror?

From 3.5 billion Reddit comments

Here's a link to the ones I use. They work well, but I don't have anything to compare to.

I bought a cheap pair off of Amazon and they are ok but not great I am probably going to get the oem replacement mirrors in a few months but they are a little pricy.

There are plastic ones on Amazon, less than $50.

These work well, easy to install/remove.
