Users say they can feel real benefits after using Circulation Maxx - with improvements in blood flow (circulation) helping to reduce swollen feet and ankles and making legs feel stronger. The instructions say you need wet or damp feet to feel the pulses in your feet so have a wet wipe or damp flannel handy. We like the fact that this machine is medically approved. If in any doubt about your health and whether you should use this, please consult your doctor. Note that it is not suitable for pregnant women, people suffering from epilepsy, DVT or have a pacemaker or similar. The only niggle about the Circulation Maxx is that you have to hold down a button for a minute or longer to make sure it reaches the right intensity level for you. If you have arthritis in your fingers and hands, this can be a little tricky.
