Was disappointed at first because i didnt get what i ordered, which is the premium 400 4 person with heater and ozone.  

Installation was easy , once filled with water it took a day to reach the set temperature(105F).
Once water is tested and balanced , its good to go.

So far im amazed with how its working, been  using it every other day , Temperature drop  to 2-3 deg in 30 minutes  with jets  on high.  I would say  its a good value for money. I would have gave it a 5 star with flying color  if they delivered it with the ozonator..
