I got it cause it looked like a good massage device at a low enough price to try out. I am not disappointed, and even surprised at how versitile it is. It is 17 in. long, a bit longer than I thought, which I like, cause it is easy to grap the 2 handles and roll the back of my legs, calves and thighs. The 8 individual rolling units are 8 inches long, and the fingers, just under an inch wide. They dig in as hard as you want to press, hard on the back thighs and calves, and easy when I go over the knees, as it is a solid plastic material, not a foam. I was amazed at the sore spots I found, and after a few rub overs, the soreness went away. It barely gets the back, just the lower back, but does do each arm. I leave my clothes on most of the time, to take away the harshness of the hard plastic rollers on my skin. Nice to have in my workout materials, and I use it more and more each time, finding new ways to rub it over , like putting it on the ground, bare feet, and rubbing each foot over it. Wow, I found I was sore in a lot of places, and after several rolls with each foot, the soreness went away-quite soothing. Looks like a super well made, rotates nicely, and solid materials, to last years, and a perfect size to easily reach to massage the legs, arms, even the lower back, and my latest favorite, the bottom of my feet.
