I am fit, healthy, and exercise almost everyday at the gym. However, a pain in the front of my leg, side leg, and groin area gradually became overwhelming painful, I could no longer walk up & down stairs. My neighbor lent me his 30 year old Jeanie Rub Messager. In 24 hours I was like new again. No more pain! Amazing! I definately recommend the product. For me, it's a must have! Drink plenty of water after using it!
Also, I bought a new model from the manufacurer. The new model is variable speed, lighter in weight. The highest speed feels like the older model. The older one felt sturdier though. All that said, I'd recommend going new. I like being the first owner.
