Hole warming accessories are few and far between and ToyDemon always welcome new attempts at warming your sleeves before use. We started the 2014 off with the USB Onahole Warmer and a couple months later, Rends has upgrade it. The new warmer is longer than the original, better built, with a longer cord, and has more points of warmth for the same price as the original. Simply plug the warmer into a usb port and insert the rod into your sleeve. Wait 1-5 minutes for the sleeve to warm up. Check the temperature every 30 sec for the optimal temperature. The actual time will differ depending on the starting temperature, usb power(USB 2.0 / 500mA on the computer or laptop required), and sleeve material. Unplug the warmer and remove from sleeve to start using your warmed sleeve. *Note this item is not waterproof. Do not submerge or rinse in water. Do not leave the item plugged in for extended period of time or unattended. Use only the recommended computer or laptop usb power level (USB 2.0 / 500mA) instead of USB wall plug. The original warmer was used in the picture inside the sleeve.
