this collar is effective at keeping your head off your chest with Dropped Head Syndrome. It is also absolutely excruciating when worn for more than about 10 minutes at a stretch. I have to wear it for hiking, walking, shopping, working, photography. It can't be worn driving as it shifts out of place. It is a constant source of misery. Being punched in the face is less painful. You have to rebend this collar every 10 minutes because the weight of your head causes it to bend out of shape. You also have to bend it all by yourself when you purchase it. Generally when I am wearing it I pray for someone to come and hit my head so hard I never regain consciousness. Adequate head support. Constant pain and misery. I got dropped head syndrome from radiation. I should have just skipped treatment and died. Would have been much better off. I would recommend this to someone I wanted to see suffering.

Works. Easy on and off. I find the material somewhat itchy on my chin.
