Here is my experience:
Restaid seemed to work the first day, but only for few hours - not 8 hours as they claimed. But, when I continued taking it on a daily basis, it lost its effectiveness and within 4 or 5 days, it didn't make any difference if I took the pill or not.
I had ordered the product through Restaid web page. When I tried to return the product, despite several attempts through e-mail, no one from customer service contacted me to issue a return authorization number. No one answers their customer service phone number either.
But, they keep flooding my e-mail with advertisements for their other products everyday.
