What to know before buying

Listing details to confirm

The listing’s temperature claims are inconsistent: the product details give a 95 °F to 149 °F range, while the feature text lists mode ranges of 104–113℉, 122–133℉ and 140–150℉. Treat these as unconfirmed listing figures. The runtime is given as 3–10 hours without a setting-specific breakdown. Customer feedback also varies on calf fit and comfort, with some reporting tightness, and some describing reliability problems after a year. Check fit and care guidance for the selected listing before purchase.
