Enjoying very much, Easy to move to location and get started, As a first time tub owner, the chemical thing seems intimidating, I may have to get local professional help before I understand everything. The temperature loss that a few people have commented on does exist. but it takes at least a half hour. by that time I'm ready to get out of the heat. Only drops 2 degrees from 102. That's with the outside air temp at 40 degrees or less.All the reviews that were available helped to make a decision to purchase without ever actually seeing one of these units. The wife and I are very pleased
