I love this! Here in Texas it is sooo hot and the summer months are much longer than the winter months. In fact, most years, it doesn't get cold until around Thanksgiving. On a regular stroller, there is a cover to offer some shade that is attached to the stroller but in some cases when the sun seems huge and it's really hot, it isn't enough. That's where the Extenda-shade becomes invaluable! It was a baby-saver at the zoo! My baby was well shaded and protected from the Suns UV rays. She wasn't hounded with direct heat either. It extends enough for maximum protection, but she was still able to look around and catch the sites. The design is very cute as well and can be suitable for either boy or girl. It's easy to use as well: just use the ties and secure it on. If your stroller doesn't have a canopy then this won't work. It goes over the factory canopy. Also, I doubt it would extend enough for double stroller, though I haven't tried doing that. The bag it comes in actually acts as a storage bag...with a handle and zipper! So if you're out and about, and you don't need it at that moment, just slip it in its storage bag and zip it up. Very convenient. I absolutely recommend this product to anybody with a little one that rides in a stroller.
