I have had CHI Institute products for 4 years now. The original Infratonic was amazing. It helped with brusies, sprains, headaches, general diffuse pain, chakra balancing and so much more. I have a Mobile Medic [Latest Version is CHI Palm] and use it for drives over 5 hours. I have a severely compromised spine and this allows me to function when I get out of the car. It is small and easy to use and transport. I have tried many modalities and “machines,” this is a proven winner.  It gets 4 four stars.
