The positive things about this hot tub is how it is made and the color. That is fine. The negative is that is takes longer than 20 hours to heat to the optimum heat. We have had it going for over 24 hours and it has just got it up to 93 degrees, We waited a long time to even get the hot tub - and we have to wait forever to get it heated up to even use the thing. The booklet said it would only take up to 20 hours to get it heated up to where you want it. The whole thing is a letdown. DO NOT BUY THIS HOT TUB!!!
