'No Regrets'

As a swimmer, I have always swam in pools or open water. I hesitated purchasing a swim spa until Covid. I have no regrets and wish I had purchased the unit years ago. It has exceeded my expectations and would strongly recommend the Challenger 18D.
- Gary, Ohio

Wish I Bought it Sooner

I've wanted a swim spa for years, and I chose the H2X Challenger 18D and love it! I'm swimming daily but I also find that there is no end to the variety of exercises I can do in my swim spa! Keeping it clean and the water perfect is easy and my dealer gave me lots of tips to make it simple.
- Liza, North Carolina

'Exceeds My Expectations'

The H2X Challenger 18D is by far the best thing I have ever purchased for myself. I swim hard and fast daily, and I even allow my family to use it.
- Swamijoe, Ontario
