Title: not great
Review: It was cheaper than the other headache reliever headband replacement inserts so I tried it. The massive gel filled tube lasted about 10 zaps and then melted on the ends. However, this worked out for the best as I filled a sock with bulk seed from WF and it stayed warm as long with no chance of melting.
