Don't trust these reviews. The spa my wife and I bought from a Master Spa "road show" has some positive features.
However, our spa came with a substandard cover (in my opinion). The cover didn't fit well and began sagging into the water after about a year. The cost of power is about two and a half times the amount in their advertising, which is much more then other spas this size. I would not buy another spa from Master Spa..
They also take down negative reviews or possibly put them at the very bottom of the reviews they receive on line. How I wish I had purchased our new spa from a local dealer.
Reason of review: Damaged or defective.
