Reviewed by John Bailey - 1st Jun, 2021 Bitterly disappointed of Quest Clamp On Sunshade. This item is not fit for purpose. It does not do what it is said it will do. There are no instructions for the user on how to get the best from the sunshade. Plus when applied to a folding chair, the clamping arrangement does not hold the shade because neither radius of it is suited to the radius that the Sunshade is being attached to.
