I am a senior citizen who flew solo for the first time to Europe. I purchased your fly kitt and neuromuscular stimulators. I am prone to leg cramp us it too long and the stimulator’s prevented that. Flying over and flying back I had absolutely no Jetlag. Everyone else on the plane was feeling the effects of jet lag, but I was perfectly fine, full of energy and started my vacation immediately. Do not waste your vacation time dealing with jet lag. Buy these products and you will be so glad you did.
