My husband George has a lot of problems with arthritis. That’s the reason we purchased the Barefoot spa. The 57LP does what we thought it would for his joint pain and soreness. We found one that was the right price, and it is the perfect size for the balcony just where we want it. We didn’t find any other ones this size with the features he wanted. My husband installed it himself and did the wires and all of that. We had to do maintenance on it only once in the five years we’ve owned it.
