I have owned the 5 person hot tub for a month now with no problems or issues.  I enjoy the fact that the hot tub turns the jets on and off automatically to save energy.  The multi colored water fall feature is relaxing especially in the evening!  The water temperature has been consistently 100 degrees when I go out each day to use it even though the outdoor temperatures in February in Missouri were quite cold even going below freezing and the water temperature stayed 100 degrees!  I have yet to use any chemicals so I assume that the Ozonator is working well to keep the water clean.  The lid on the hot tub fills well and comes off and on easily.  I was able to set the tub up myself and was able to move the tub from the front driveway to the rear of the house by myself by making a cardboard sled using the cardboard the cover came in and pulled the tub around the house on the cement walkway that goes around my home.
