I would have rated it 5-stars, but there is only one problem in the comfort department. The jets near the head rests are not recessed enough and you can feel them in your upper back when reclining.
Yes, I recommend this product.

I love the Kauai Spa. It fits our needs perfectly and is much more usable that a larger spa we had before. My biggest complaint is the Spa Frog water tratment system. It obviously was not designed for this size spa. Even at it's lowest setting the bromine is way too much. I have to continualy turn the bromine cartrige off completlely to let the bromine level come back down. At a setting of 1 (the lowest) it will climb higher and higher. Other than this one flaw it is the perfect spa. Too bad they didn't design the treatment system to go with the smaller size spa.
Yes, I recommend this product.

This is our first spa and it is sized nice for 2 people,it fits our needs very well. For three to use this spa would take a lot of water volume management because of its depth. But the depth is what makes it ideal for our use. Beside ease of entry, the size makes it possible to install in places where larger spas won't fit.
We are very pleased with the Kauai Spa.
Yes, I recommend this product.

The circulating pump has been replaced 2x a year since the date I purchased it.
When the warranty expires I am sawing it in half and putting it in the dump
No, I do not recommend this product.

It was hard to justify the expense at first, but it was well worth it. Small size so lower energy costs and it has great features like the wrist jets! I wish it had a couple of leg jets for the lounge seat like their bigger spas, but it may be asking too much. Anyway, definitely a great purchase! I love spending time outside soaking in my Kauai! It's like a taking a vacation without leaving home.
Yes, I recommend this product.
