We love our new hot tub! SilkBalance has made all the difference in the world. No more chemical smells or tedious testing. It is easy to use and our tub always smells fresh and clean… and the product auto refill program helps us keep it that way! A big thanks to Don Riling our salesman who was very informative, professional, patient and helped make our experience so good we now enjoy the new ownership of a beautiful Finnlio Sauna! Life is good! Sincerely, Bob and Teresa Glenn Olympia, WA
