Great jacuzzi.  Much better than the previous plug and play we had.  Right now we have it plugged in to regular power but electrician will be out soon to convert to 220V.  Temp goes down about 1 degree for every half hour of use in 60ish degree weather without 220V which isn't really too bad. Warmer climates may be able to get away without 220v. Good power on the jets, comfortable seating, filtration seems decent.  Was not too heavy to move to location and set up with two strong backs working at it and dolly.  Electronic interface is a little confusing for programing, not intuitive and the manual that comes with it isn't much help, that is my only complaint. So far so good.
