Pros: Mostly positive reviews on the EZshade. Blocks out %99 UVA/UVB. Doubles your shade to keep you much cooler. You can gradually move the hanging shade sun shield as the sun moves, rather than re-adjusting the entire pole and umbrella.
Cons: It is slim pickings on negative reviews for this particular umbrella. The only thing I could find was a customer being disappointing to find that it does not include stakes to anchor the pole to the ground. However, I believe that is what the sand at the base is suppose to be for.
