Sleek and compact, the size of an MP3 player, this state-of-the-art, quality device is small enough to take anywhere. It has an internal rechargeable Lithium–Ion battery. There are nine different modes including an acupuncture mode. It also has a tenth mode rotating through the other nine which eliminates the brain mapping the pulses. The animated LCD screen ensures you get the exact type of setting you want. Dual outputs with individual intensity controls maximise the benefits by allowing you to treat two areas independently or two people at the same time (e.g. when you are flying). It is also equipped with a timer that will automatically turn the unit off when your session has ended.
