I have had my Master Spa going on 5 years and I have had nothing to be fixed of any sort on this. I own a 2009 and the family and I love it.
We have family that come from out of town to use it or just to hang and have good times.
Those of you that complain should give it a little the company will fix what is promised or warranted to you.
They are a busy company and lots of people and companies still want, what you keep complaining of. The hot tub of someones dreams just not yours.
Reason of review: Good quality.
