Someone used the Jeannie on me 2 months ago, and I loved how it felt and got one.  I have used it on several of my massage clients and so far everyone has loved it too.  Now when I travel to see my grandkids, I take it with me because they love it too.
The only downside for me is the weight of it when I'm using it on someone else.  I can only hold onto it for about 5-10 minutes before I'm feeling discomfort in my back.  So I just have to use it on myself when that happens!  Because of its weight, it's not that easy to use on myself on the backside where I need it the most.  
Regardless, I have already recommended it to many others!
