I have had the BEMER in my possession for a month now and I must say that I love using it. I did not have any severe presenting complaints before I started, but I have felt benefits nevertheless. More energy, more stamina, less back soreness, increased clarity of mind and memory retention. And just being able to look forward to lying on it for eight minutes a few times a day is such a lovely break. I am sensitive enough to be able to feel it working on me, like slipping into a warm bath. Delightful!
