My first experience with the BEMER medical device impressed me because it created a dramatic improvement with the level of discomfort in my knee. After having the BEMER applied for only eight short minutes, the extreme irritation and stiffness in my knee was reduced by about 50%. I also noticed that after a few hours had passed that same day, I was experiencing almost no discomfort in my knee anymore. The session had a log-lasting effect, which has been great! I am a big fan of the BEMER technology.
