One of the best back massagers I've seen. I especially love the car adapter. I can take this with me on long trips when I need it the most. Another great thing about this massager is the automatic shut off. There are times I may forget to turn off the massager, but this feature I no longer worry about it. My husband and sons have also enjoyed this product. My husband has chronic back pain and this has soothed his back more than any other one we've had. It doesn't get too hot or feel too intense. I also love how compact it is. It easily fits into a suit case or travel bag without taking up much room. One other great thing is the fact that there is a 3 year warranty included. I would definitely buy this again!
