Review (3/5): Not pneumatic
This brace is not adjustable by air. One picture shows an air tube. No pump on it, no air bladders. I will wear it a day and see what happens. I would pay a bit more and get the more quality one. Read the reviews. Also, usage and your level of pain/ issues will also determine whether this is right for you. If I were working, I would pick a more sturdy and adjustable one. Air bladders might be best for someone looking for a very tight fit and looking to immobilize motion of the neck.
