Is heat a meaningful feature on a neck massager?

Reviewers consistently describe heat as a 'nice to have' rather than a primary buying factor. The warmth helps muscles relax into the kneading and feels comforting, but most retailer reviewers note it's gentle warmth (around 100-113°F) rather than therapeutic heat. If you're choosing between two otherwise similar models, pick the one with heat - but don't pay a large premium for it alone.
