Got it on sale, great value. Had it about a month and everything working great, maintains 104 with the lid on, even in a -20 degrees Canadian winter. Drops fairly quickly when the lid comes off but youll get a good 30 minute soak before it cools off too much. My only complaint is that they are very shallow compared to a traditional hot tub. Its fine when youre sprawled out but they are very shallow. Would recommend for anyone looking for a light weight relatively inexpensive tub. Does accommodate 4 adults.
