Well so far it is okay, but it has been 2 days and we still only have the water warmed up to 97 degress.  I was patient for the original 20 hour warm up wait I expected, but I am getting a little tired of waiting.  I hope the temperature maintains well after it finally reaches 100+.  The set up was easy and the hot tub looks great.  Haven't used it yet, but I plan to soon.  Fingers crossed.  I hope.  :)

Update: Once it reaches temperature, it's great!!  I am changing my review to 5 stars because I have really enjoyed this spa.  I also finally have no more back pain and my blood pressure is down which spas are very good for doing.  It maintains temperature well if you keep it covered in between uses.  Very very pleased with this purchase!
