We have had our Cordoba hot tub only a few days so I can't speak to dependability or longevity, but the initial impression is very positive. It is indeed plug and play, in a 110/120 outlet. It filled in an hour, heated up yo 104 in about 12 hours, and is ideal for our needs. It just fits two people, and the jets are very good (given the size of the tub). Over 20 minutes or so the temperature drops about two degrees, since the 110/120 power won't run the heater and jets simultaneously. We have a very narrow space, and I never thought we'd find a tub that would fit. This one is perfect!
