Not sure how widespread the advertisement campaign is but I have been listening to the comercials on the radio and saw them on TV. I wake up several times a night with shoulder and neck pain and numbness. I took a gamble and paid the $64. I used the pillow last night and woke up this morning with no pain at all, my fingers are not numb and tingling either. If you have been thinking about it do it you won't regret it.
My girlfriends mom has one and hates it... Doesn't work at all for her issues. I am still tempted to get one, but I really don't like super soft pillows (from what I've seen it looks that way).
I need to replace all of our pillows in our master BR, might invest in one... about time to replace the mattress as well eek..
