I wish I could give 10 stars for this spa! We purchased this spa for therapeutic reasons and we couldn't be happier. It's easy to set up and is very attractive, much better quality than I was expecting for the price. We paid an electrician to bring electricity out to our patio. It filled quickly, and took a day to heat completely. I was worried it would be difficult to maintain, but I can drain and refill easily without hassle.  We were worried about high electric bills, too, but have noticed no difference. The lid is attractive and insulates beautifully. I can't wait to use it this winter when all the aches and pains set in!
