We are very happy with our purchase.  It does cool down a bit after 15 minutes, but we live in oregon where it does not get very cold so it is fine.  Also, the cover was damaged, but Wayfair was very quick to respond and sent us a new one right away.  Their customer service was very customer friendly.  We were worried to make such a big purchase on their website, but now we know that they stand by their products.  Thanks Wayfair!
