I really like this hot tub, though am not loving it. I waited a couple months after having it to do the review. We had a portable hot tub previously, our electric bill was not extremely effected, with this hot tub it has gone through the roof! We live in a cooler climate though it is not exposed to snow or rain. Another thing all of our jets don’t work fully on one side.. hmm. 
I would have given it 3.5 but that’s not available.
