23. How does it work?

26. A Patient’s Story “ July 19, 2000, I had my first operation due to blood clot in my leg. I needed a second operation, but my leg and ankle were too swollen for surgery. About July 26th, I received a FlowKeeprs and used it about seven or eight hours a day. It helped to reduce the swelling in my ankle from 27.5 to under 24cm in circumference in about five days and I could proceed with my surgery. About two weeks after my second operation, my leg got swollen and painful again. Around August 8th, I was able to use the FlowKeepers again when my surgery wound closed. It helped to keep the swelling down and reduce pain so I was able to walk around. It reduces my need for pain medications and I am still using it for 5-6 hours a day. Today, one year later, if I do not use FlowKeepers for one or two days, I notice that by the end of the day, the swelling and pain has returned.” Geza Toth Fairfield, Connecticut

27. Amiram, The FlowKeepers device worked like a charm! It worked flawlessly the entire (flight) duration of my recent trips to Spain and Calgary. It provided great relief as my ankles were not swollen at all. A true test of its effectiveness! Even while sleeping, the device is at work. All I am required to do is turn it on and off and the device does the rest. Remarkable!! I continue to read with great interest the best advice to combat this dreaded ailment ('Economy Class Syndrome') but am now more than confident that you have a winner. I have recommended this product to all of the travelers in my office. Louis A.
