Review on Universal Holder Rearview Mirror Samsung by Brad Collins

Straight to the point: it depends on the shape and thickness of your test mirror. If the top and bottom of your mirrors aren't 100% straight, they won't hold up. Although the product itself is well made, after 2-3 hours of riding the grips slip around the curves of the mirror (see photo of my curved lower mirror). The second factor is the service box, which usually surrounds the rearview mirror. Most new cars come with a box that usually contains the wiring that powers the monitors around the mirrors. This makes it difficult to place the product closer to the center, which prevents slipping.
