well the thing that I was disappointed in was the instructions from the manufacturer,  the booklet that came with the hot tub was totally incomplete.first my unit was not listed among the model numbers listed, second the instructions in the booklet say never plug it into an extension cord,this will invalidate your warranty well if you read the description on the wayfair website it says plug n play even plug it into an extension cord. The other thing that  was not in the instructions was that when you took the side panel off to check for leaks to in tie the cord to pull it out and that the light was not hooked up. it tells you how to change a burnt out one but not to hook it up initially, but my wife and I do love it and would recommend it.
