Product Review (submitted on March 5, 2013):
Just wanted to say WOW!! The quality, attention to detail, customer service and shipping can only be described as excellent! I now feel comfortable leaving the spa in service all winter not to mention how much better my back yard looks. You definitely have a repeat customer!
