Review on 🔍 K-Source 3791 Universal Clip-On Towing Mirror: Boost Your Vehicle's Fit System for Optimal Performance by Rick Ross

I'm using them on an SUV that I can't buy custom mirrors for towing an 8ft wide trailer. With my standard mirrors alone, the outside edge is only about 2.50m which means I can't see anything from the side of the trailer, especially with the driver's side mirror. These mirrors are very easy to install. Just a suggestion, measure the elastic on them before you attach them and then tighten them a bit. When you put them on, you should tug on the elastic a bit to secure them and make sure they're snug. The mirror can be positioned in both landscape and portrait format. The only thing I don't like about them is that they vibrate a bit at highway speeds. While not too bad, it's certainly noticeable when looking at oncoming vehicles from the side of a trailer. Like I said, it's not that bad, and the convenience of seeing my trailer certainly outweighs the slight vibration I get from these mirrors.
