Product Review (submitted on November 22, 2013):
This cover is so much better than the original one that was purchased with the Hot Tub! It's well made, and Very attractive Looking! The website was easy to use, and their customer service personnel was the Best. Will definately recommend them to any and everyone. Thank you so much!
