Review on Enhance Towing Visibility with Snap & Zap Custom Fit Mirror Pair for Chevy Silverado 1500, GMC Sierra 1500 by Jonathan Devarapalli

These mirrors are perfect for the 2020 GMC Sierra. They look good but aren't long enough. They don't increase the field of view enough to justify the cost. Once on the OEM mirror they don't vibrate much and visibility from the mirror is good but it doesn't extend far enough to be very useful, especially from the passenger side. It helps a little on the driver's side, but not enough to justify the mirrors. If I had to do it again, I would try a different mirror.
