Nice little hot tub. Have it running off of a 110 circuit. Heats up within 24 hours, Jets are very strong and holds temperature. After 30 minutes temperature only drops 2° In 30 degree weather. Why the four star rating then you ask? I dare anyone to take off the access panel. It took me 40 minutes to get it off and back on again.There’s no way it should be that aggravating to take out seven screws and put seven screws back in. That part of the hot tub needs some serious re-designing. Other than that so far so good.
