do not purchase from Neckline--Buyer beware
I ordered this product on a facebook website
My wife has very bed vertigo and neck pain
the product took a few weeks to come--they never say its coming from China We were hoping this product would help but quickly realized it was a piece of garbage
They say they offer a 30 day money back guarantee, i sent them an e-mail stating it hurt her neck and was useless i got an e-mail back after threatening i was going to dispute the charge with American Express
and start giving them bad reviews on social media
they emailed me back offering me 40% off or i can ship it back to China at my expense without even telling me where to ship it back to
