Rated 5 out of 5 by from I love my swim spa This spa is a delightful escape from the real world. I live to spend long periods of time exercising, stretching, soaking or just thinking in my spa. In the morning, I have my first cup of coffee in my spa. I wake up and listen to the birds, watch the sun come up over the fence and see the sky come alive. I then put on my goggles and snorkel and swim in place for 30-40 minutes. I will relax and stretch before getting out and going to work. My spa is easy to care for. I test the water after each use and add a little chlorine. Once a week I check and hose off the filter. It stays remarkably clean with clear water. I do use an all-in-one product to maintain all chemicals in balance. I do love my swim spa.

Rated 3 out of 5 by from Not exactly what I expected The swim spa is built well and operates/heats efficiently but there are a few issues with the use of the unit. The jets which provide the resistance to swimming only operate on two speeds. A variable speed adjustment would work much better as the low speed is too low and the high speed too high. The hydro chairs get in the way with your kicking stroke while swimming so would have preferred they were smaller or not there at all. The unit came with a tiny set of stairs which were nowhere tall enough to be able to enter the pool. Had to build stairs to get into the pool.

Rated 5 out of 5 by from Can't live without my swim spa! When I found out we would be selling our house and moving 1500 miles, I said we really have 2 options: sell the swim spa with the house and buy another one once we've moved, or move it...those are the only 2 options!

Rated 5 out of 5 by from No Regrets !!! I am so happy I purchased my swimspa. I had considered an inground pool but the following reasons cinched it for me with the spa: *limited yard space *saved time not running to the gym *year round use as I am in Ohio *workout equipment included (rower + resistance bands etc) *swimming is low impact as I had injuries *spa is glorious-jet tub after workouts *minimal chemicals needed *very low energy usage *ease of use * total relaxation after a hard days work=mental health *more affordable>> My suggestion: "Go For It"

Rated 2 out of 5 by from To short to swim Was disappointed that I could not swim in it! I am only 5 feet 6 inches. WOW! Have had it only a week and it's good for the kids, but not adults. I am the shortest adult in my family, we tried it with a 6'4" adult and a 6'2" adult. They were hitting the walls and water blown in their face. Go for a longer model if you have tall teens and adults going to use this to swim. Also we did not receive instructions on how to turn what knob to get what jet to turn on or off.

Rated 3 out of 5 by from Like the Spa but Had Issues The delivery and setup was great. The guys were very good. As soon as I filled it with water, it leaked out of nearly every jet. I called the dealer and got a sales guy. I also emailed the dealer and Master Spa and got no reply (disappointing). The sales guy sent a ticket to a repair company who came out several days later. The repair person was very good and fixed the issue.

Rated 1 out of 5 by from Should NOT be marketed/sold as a "swim" spa. Stationary exercises are about the only thing you can do in this unit. I'm 5'4 and my feet continuously hit the seats in rear, plus the jets propels so hard making it very difficult to stay in sweet spot. NOT LONG ENOUGH FOR SWIMMING.

Rated 4 out of 5 by from No regrets Great size for folks under 6 feet. I can swim but my partner cannot as his arms are too long. When I purchased, I was told the spas was easy to maintain. This isn't necessarily true. I'm using more chemicals than they told me in order to keep it from foaming and turning green. Great way to get low impact exercise and relax. Can't wait to try it in the summer
