My husband and I have been using the Laser with great results. Most beneficial has been for my mum with advanced dementia and complete immobility. It has been an incredible aid in relieving neck and back pain. She is now able to turn and move her head after a treatment. She can barely talk but I ask her is it helping and she says yes. This is remarkable as she generally is not able to communicate. It’s a godsend product for us thank you so much.
