Your neck is tight right now, isn't it? Consistent poor posture can cause "tech neck" from looking at your cell phone, computer, reading books, and even driving. This can lead to extremely tight neck muscles and headaches from the tension. The 4" Chirp Wheel XR massages the suboccipital trigger points in the back of your neck, releasing tension on your neck and shoulders. This will reverse the effects of tech neck and will make you feel much better than you do right now!
