We really enjoy using our hot tub outdoors during the cold evenings. It is so relaxing sitting in the warm water when the air temperature is below freezing. We have had it for one month and no issues yet. The wide variety of jet configurations suit the needs of different users nicely. The ACE system is great, I don’t need to mess with chemicals which is one of the main reasons we purchased this brand of hot tub. The minimal energy usage was also a big factor in deciding to go with HotSpring too. LOVE IT!
