Well then, I saw this ad on tv.
If you're trying to sell a pain relief item, maybe it wouldn't help to make the claim that "Nothing's been proven to beat the relief." Sooo, nothing will help. Don't bother buying this product.
They should have run this campaign through a consumer panel first for feedback on just how negative this makes their product look.
FIRE YOUR ADVERTISING AGENCY!
Sincerely, Me (a consumer who now would never buy your product)
