After a lot of online research, we finally decided to pull the trigger on our new Jacuzzi J-315, and it has been PERFECT! We have had the hot tub for about 5-6 weeks, and our enjoying it about 4-5/times per week. Living in Phoenix area, we went with 110v option (it doesn’t get that cool here, haha) and so far so good. We have 5 stage filtration, and are using essentially all natural products to treat water, still getting all that figured out, but so far so good. Jets are positioned perfectly for my wife and I, and we both can really relax in this hot tub (which is one of the main reasons we bought it). Looking forward to the winter months here, and probably using it even more than we do now. Highly recommend Jacuzzi to anyone out there looking for a high quality hot tub.
