Santamedical Mini Penguin Massager with two modes, White

I ordered this for my husband who suffers from tension headaches due to his line of work which is a conductor for the railroad. Long 12 trips cause him horrible tension in his neck giving him headaches. Unfortunately, he cannot take his muscle relaxers obviously due to operating at work. This mini massager is only 6.1 inches which is perfect and compact to carry on with him. When he starts to feel tension he turns it on to the high setting massaging temples forehead and neck. It has two settings (high and low) but his is so tight he must use high all the time. Operating with only two double A batteries makes it nice because he uses rechargables and charges them as needed at the motel. Yes, he uses it that much he keeps batteries available. He said it's been a miraculous little device and now recommends to his fellow employees struggling with the common tension headache. Would make a great gift as well. I hope this helps!
