It should get manually changed by them within 24 hours. **Q: Why is this listed as a men's product?** A: We are forced to tick boxes otherwise products will not upload onto the platform. There used to be a unisex option but that wasn’t offered... **Q: Does it maintain the same temperature or does the temperature fluctuate?** A: Hello Sam, the hand warmer has 4 different heat setting, once the device reaches the required temperature for the setting you are using, the temperature will remain constant. Hope this helps. **Q: Is this waterproof?** A: It is weather resistant,, not water proof… ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great. *by C***S on 1 March 2026* Brilliant bit of kit.
