Rated 5 out of 5 by from Love the swim spa I purchased my swim spa for health reasons. Once I began using the swim spa I loved it. I couldn't wait to get in and begin exercises and use the jets. I began feeling better and sleeping better. It has truly been a life saver. It is wonderful to have it right outside the door where I can just get in whenever I want to. Just floating is so relaxing. It has been the best thing I ever bought for myself. Thank You

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 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

Rated 5 out of 5 by from It's awesome This swim spa is far better than I could have imagined! I really love it, so much easier to maintain than a pool, and it fits on my porch, and now I'm making a sun room around it, so I can us It year round. I love the excerise equipment you can get for it, great all over workout, no stress on the joints anymore !! So happy I got it, very sturdy construction, and the roll up cover is perfect and easy to roll out of the way. And all the clips have locks in case you dont want a kid falling in when your not watching. You won't be sorry if you decide to get one as well. So many different ways to use the jets, it's hard to decide sometimes. Seats are comfy with lots of jets to focus on any part of your body that's needs attention. Go for it you'll love it!!!

Rated 1 out of 5 by from After the tub arrived, it did not work right. The hot tub from the get go had major problems. It would not run. I communicated with Master Spas and nothing helped. I had 3 electricians work on the power source. I paid for all of this. Finally, master spa gave me the name of a technician that had been associated with Master Spas in the past. He happened to live in my town. Another problem--there are no techs to service "problem" tubs. He lives in Hood River Oregon and people from Spokane, Washington have called him for service. Hundreds of miles away. I know that at first a motor was replaced. Finally the technician replaced the whole mother board including heaters. I covered all of the costs on my own, after the motor replacement. The hot tub has worked fine after all of that. My recommendation-- don't go to a spa show and purchase this brand of hot tub, no matter what Michael Phelps says. My H2X Trainer 12 was a night mare.

Rated 5 out of 5 by from Love, love love it! Swimspa is awesome! Spend the extra and get the lights, Bluetooth, etc. So worth it! Live how I can exercise and relax and swim tear round! Better than dropping the money into building a pool. Especially when we would only use it 6 months out of the year. Now remember there's those extra costs with crane, running the 220 line etc...Well worth it!

Rated 4 out of 5 by from I really like my swim spa I spend 2 hours everyday doing various exercises and weight lifting. I had intended to use the swimspa to walk in-place however, it is not deep enough. I assumed the 51 inch depth was the water depth-which would be perfect. Even though I can't use my swimspa for the intended purpose, I still like it.

Rated 3 out of 5 by from Could be much better!! The spa is very nice once you're inside and enjoying the Jets to massage your sore muscles. But a few issues on the height of the head pad and the jets in coordination with the average body size. In other words you can sit down and get a nice massage but your head will not be on the head pad. As a matter of a fact you can sit a five year old inside of the spa and they will have the same issue which is so weird. The next thing is it has poor lighting and no light next to the rainfall. And the rainfall cannot be turned off separately which would be a nice feature. If you're sitting to the left getting a massage then the water from the rainfall is splashing in your face. The exercise equipment is a joke. But don't get me wrong I do love the spa I just don't like the design and the placement of several things inside of the spa. And the control pad is a very cheap design. When you want to control something on the pad sometimes you have to press it pretty hard. I'm sure eventually the control pad will give out.

Rated 3 out of 5 by from Pluses and Minuses The pluses: it looks beautiful and swimming is great fun. The minuses: installing in ground took a hurculean effort and cost. The controls, both electronic and manual, have been a challenge to learn. It is extremely slippery getting in.

Rated 4 out of 5 by from Exercise on my schedule I love my swim spa and the flexibility it gives me to swim and relax on my time schedule not some gyms. It is a great investment.

Rated 5 out of 5 by from Best of Both Worlds The Trainer 12 makes exercising fun and painless. I've never in my life looked forward to exercising until now. One of the best parts: you get to sit in the relaxing jets when you're finished! Another plus: it's October and everyone here is closing up their swimming pools for the winter, but we get to continue enjoying our spa. Can't wait to go for a nice swim in the middle of January!

Rated 5 out of 5 by from Enjoy it I really enjoy the new swim spa. the only negative thing I have to say is about the instructions for the spa itself. the book never really tells you how to use the controls for the water/jets. the book talks about chemicals and the controls, but not how the power controls controls work for the jets. you have to just get in and figure it out. other than that, it is great.

Rated 5 out of 5 by from Nearly 5 years old! I love my swim spa. Purchased nearly 5 years ago off the showroom floor at a convention center sale in our area. My only complaint is that there isn't an area rep to help with our first warranty issue. Master Spa took care of us by mail and email! Just got on the site to look for a new cover. The Axis looks like just the ticket!

Rated 3 out of 5 by from It's a good swim spa. They didn't tell us that there are different instructions for cold weather start ups so when the thing didn't work once 950 gallons of water was in it at 10 below zero temps I was extremely upset. I called the guys that I purchased from cell phones since the company closes at noon on Friday and this was at 1:30. They got me in contact with a manager and that is when we found out we had to unthaw the spa first. So to the store I go to purchase a nipco heater and some propane tanks so the water doesn't freeze. Two hours with the heater on the pumps and they finally start to work. It takes two days for it to push through and the swim jets to let go and begin to work. Now I'm trying to get the PH levels right and I can somewhat relax. The electric bill better not make me sick.

Rated 4 out of 5 by from Better than a pool! We purchased a swim spa for year-round use of exercise and recreation. We love the jacuzzi seats with heat in the winter. In the summer, it's the perfect cool down with the heat off. We had a deck built around it to minimize the size of it. However, our propulsion went out in a few years of owning it. The cover does get heavy, and ours was damaged by hail. The rest of it works great! It's been almost 10 years now. I would certainly recommend it.

Rated 5 out of 5 by from In it Every Day! We are in our swim spa every day... sometimes two and three times. It's so much better than having a pool or hot tub. Pools are too much work, and go unused. I used to have a hot tub, and used that daily... but being able to stretch out and swim in the swim spa is so much better!

Rated 5 out of 5 by from Year round swimming inside a new Patio Home We designed and built our new patio home around a Trainer 12 in a separate room attached to out Master bathroom. We lowered the concrete floor where the spa sits to provide only two feet above finish floor. After swimming we take a shower and go to bed. How relaxing!!

Rated 5 out of 5 by from Love our Swim Spa!!! It took quite a bit for my wife to convince me that buying a Swim Spa was the perfect fit for us, but the Master Spa Trainer 12 that we purchased was a great price and the best buy for your money guaranteed. We use it almost every day and love it!

Rated 5 out of 5 by from I love my swim spa! The swim spa is excellent and beyond our expectations.Eight people can get in it with no problem. And there are jets everywhere.Also we can't believe how strong the jets are to swim against. As my little nephew says " it is awesome!"
