Excellent Spa
We have had our spa for about three months now and we thoroughly enjoy it. We have some health challenges and getting into the spa for therapy has been extremely helpful. Our grandchildren love to come over and enjoy the spa. With small grandchildren, the lock down features are greatly appreciated. We are pleased to see how economical it is. We expected higher power bills, but the amounts were lower than we anticipated. The only challenge we have had is learning how to regulate the chemicals.

New morning tradition
Every morning we use our hot tub and drink a cup of coffee. What a way to start your day! It is energy efficient, only increasing my electric bill about $10/month. I know others who purchased their hot tub from a home improvement store and cannot use their spa due to the large increase to their energy bill. The chemicals are easy to add and I purchased a paradise spa vacuum to clean the seats of grit - what an easy chore. It seats 4-5 larger adults comfortably or about 6 teenagers. Now my back feels better, my pocket book did not take a large hit, and my husband and I have a new morning tradition.

Backyard Luxury
It's been nearly two years since we took delivery of our Marino spa by Caldera. We use the spa at least three times a week. We used to book a hotel every once in a while to enjoy relaxing a bit and using a hot tub. Now we just step out our back door and mmmmmmmm! we're in the lap of luxury and we can sleep in our own bed. The spa has performed like a charm, without one hitch since we plugged it in.
