Fantastic, but big.
This massager works my neck muscles better than any other massager I've ever owned and is specifically designed for the neck. In just two weeks my neck is looser than it has been in several years. The device is large however. It also has batteries, or else it makes its own power out of nothing. Just kidding. I didn't realize it had batteries until I used it on my neck and then noticed it wasn't plugged in. Great device.
