Title: Doesn't hold the heat!
Review: I had high hopes for this product, especially given the premium price. It arrived very quickly from the seller and with excellent packaging. However, usage has been very disappointing ... it just doesn't hold the heat very long, and certainly not for a 20 minute therapeutic session.I rarely write reviews, but felt strongly enough about this product that I wanted to warn others hoping to find relief from chronic neck pain.
Is the review positive or negative?
