Review on Ultimate Protection: 2-Pack Car Side Window Sun Shades - Universal-Fit for All Cars - Easy & Effective Solution to Block Sun Glare, Harmful Heat, UV Rays for Babies or Pets - Black Static Cling Film Design by Jon Brazil

These are the best shades I have ever used on my SUV. Holds up beautifully (tested for over a few months), easy to apply, can be removed and reapplied. I've done this several times and moved it around windows. In addition, the membrane is thin enough and does not interfere with the power window assembly. Effectively blocks light and does not block the view. My children are especially grateful for this on long journeys. The only thing I would wish for is different sizes as they are too small for my SUV's rear windows. Super happy though.
