Awesome Spa - HIGHLY RECOMMEND!

"The Twilight Series 87.3 model by Master Spas is one-of-a-kind in my opinion. My wife and I shopped for spas for months looking for a high-quality product with his & her lounges. Trust me when I tell you that there are very few options on the market. I am 6'2" and my wife is 5'3" and the 87.3 is the perfect solution. This spa seats 5 comfortably and the 49 jets really pack a punch (most are adjustable) to give you a true therapeutic massage for those sore neck, shoulder, back and leg muscles. We pretty much use it daily and we're very thankful we chose a Master Spa!" - Scott, Arizona
