We have had our hot tub for 3 years now and are extremely happy with the Caldera tub we purchased and the service we receive from the entire staff.
I bring my water in for testing every two weeks and am promptly shown what Chemicals I need to add to keep my water balanced. This makes having a hot tub worry free.
Also, anytime I have had a question I receive an answer quickly.
I would highly recommend buying a hot tub from this company!
