Read the warrantyThe warmth goes up to 42°C (107°F) and helps tight neck muscles relax. There are two heat levels, so you can choose the lower one.
It turns itself off after 10 minutes. If you fall asleep on it, it won't keep running.
There are three intensities: Gentle, Moderate and Intense. Start on Gentle, and stay on it if you're using Hizoo for puffiness.
Dr. Brandon Bridgeman, a sports chiropractor, shows how to place Hizoo on your neck.
You lie back so your neck rests between the two tall, rounded prongs, just below the base of your skull. The four nodes knead the muscles there.
It should never press on the front of your neck. If you feel it there, or behind your ears, sit up and move it a little lower.
I have come to love the Hizoo
"In all honesty, I hated the Hizoo my first few days because where it was massaging kept hitting the bottom of my skull area and it hurt a lot. I will say Hizoo has the BEST customer service and they sent me a tutorial/video on what to do if it is not massaging in the right place. They have been super helpful and concerned. I have come to love the Hizoo and use it 5 minutes a day twice a day just to work my way up!"

It can feel strong the first few times, especially if your neck is tight. Start on Gentle and keep each session to 10 minutes. Firm kneading is normal. If it ever feels sharp, stop or turn it down.
It can happen in the first few sessions. Slip a thin pillowcase over Hizoo, stay on Gentle and stop at 10 minutes. If the marks don't fade, take a few days off and email us at support@hizoo.co.
