Some have mentioned that it's a pain to put on and I actually want to challenge this. I believe this device went far above and beyond to make it as easy to deploy on yourself as possible. There are the neck stretcher pillows out there but this one does such a far better job because it's a full-on brace. It takes a few uses but you can quickly learn where the latch is to close it. And if it's tight against your chin, you likely need to tighten the brace around your neck (with an easy-to-find knob on the back) before inflating and stretching. Similarly, the OPOME neck stretch adjustment is simple. Each side has a tactile 'bump' (kind of hard to describe) to make sure you adjusted both sides equally. To be most effective, here's what I have recommended from my own experience as well as my Dr's advice (which this isn't medical device, just my opinion): - Sit still. You CAN use it moving around and stuff, but think of this as retraining your muscle memory...
