I installed Swiss Harmony just four weeks ago in my apartment, but this much I can say now:
My tinnitus has clearly decreased and I only have it when I am physically not doing well.
However, my general physical condition has improved significantly. I feel healthier overall and do not react to the radiation from the computers and televisions like before.
I also sleep much deeper and feel fitter in the morning. I am better and faster on my feet.
Overall, I feel that I can relax more easily in my apartment since it is harmonized.
