Bought it for my son and he loves it, took a few times of using it to notice a difference but it does actually work.

This little device is great if you suffer from sinus migraines. Sometimes when a bad one comes on I have to use the rolling massager on my back and this at the same time. I look crazy but there's some relief!

I bought this for my wife who suffers from migraine. It’s helping a lot, she uses it at the beginning of a migraine attack or whenever she feels that she might have a headache. It’s really working and helping her relax and manage her migraine, she’s been better since started using it. It’s a little bit noisy, but she doesn’t mind it now, got used to it. Highly recommended.

I use this all the time now. It helps correct my posture so much and alleviates pain that gets exacerbated from working on a desk all the time.
