Awesome little spa.   It was delivered on Tuesday and it took about an hour to set it up and fill. By Wednesday early afternoon it was at 102* and my wife and I enjoyed it that evening. We ran the jets for 30 minutes and it never lost a degree temperature wise. I’m not really sure why we waited so long to buy one. The interior surface is a little rough, but I think that helps to keep you in place when the jets are trying to push you off your seat, as they are pretty powerful for a 110 plug and play pump. All in all, I’m quite pleased. I’m anxious to use it during the cold WENATCHEE winter and see how it holds up. I’ll let you know how it does in the 20* snowy winter weather, but for now it’s pretty darn nice.
