We originally wanted to give this 5 stars. The first time we put it up at the beach in NE Fla., it worked great, it made a huge shade space and the wind cooperated beautifully, blowing through the canopy just as pictured. We were the envy of other beachgoers struggling with umbrellas and 4-pole pop-up tents. However, visit %232 was the opposite story. We carefully checked which way the wind was blowing, and put the front of the canopy facing the wind. But wind can change on a dime, and did so. The 2 curving, segmented metal rods that form the semi-circular support went up easily, but before we could secure the guide strings (with sandbags at their ends, to hold the blue nylon up) the wind began blowing through the BACK of the structure--pushing the "flapping" part of the blue nylon through to the front! The "walls" of the canopy were caving in as the wind blew first one way, then the other. We sat inside with the blue nylon covering our heads :-), laughing helplessly as it blew in our faces here and there. The sandbags were useless. We were so hot and tired by the end of that hour, we took it all down and went home (fortunately, 5 minutes away). Pick a day when the ocean is just breezy rather than windy... or a lake or other setting without gusts. When not battling high winds, we found this canopy easy to put up (%26 take down), and it gives a huge shaded area. It was reasonably priced (about $50), and not heavy to carry in its packing bag. One tip: The black "guide strings" need to each be wound up and secured with a rubber band separately after each use. After the first time we failed to secure each string separately, we found a pile of black spaghetti in the bag that wasted 30 minutes of unsnarling. "Live and Learn"! We still love this canopy, and do recommend this unique shade canopy over typical beach umbrellas or pop-up tents.
