Our tub was delivered in May and our family has since averaged about three to four nights per week in the tub. Needless to say we LOVE our hot tub. Friends had warned us about hot tubs leaving their skin feeling dry and itchy, but with the Silk Balance system we haven’t experienced any of those problems. In fact, we’ve had some of those same friends over and even they have commented on how our tub leaves their skin feeling soft and smooth. Silk is a great product and I would highly recommend it.
