How to choose the right torso sex doll heating rod?

Whether you are a beginner or an experienced user, I recommend an automatic heating rod. It solves over 99% of your problems: uneven heating, uncertainty about heating duration, lack of warmth sensation, damage to the gel from overheating, and the need to constantly monitor the heating process.
Some people wonder: "It's just a heating rod, what can it do?"
Automatic heating rods are indispensable. Their core function is automatic temperature control. As the name suggests, they are equipped with a temperature sensor that detects the temperature of the connected cup and automatically turns off when necessary!
Simply plug in the heating rod for daily use, connect it via USB to a power source (socket or power bank), and wait for it to heat up. You can then use it as usual!

Why do heating elements damage dolls?

Many torso sex dolls are made of flexible TPE. This material is soft and flexible, simulating a realistic feel without excessive oil production.
The heating rod, however, is not heat-resistant. The recommended temperature is usually between 30–40°C. While it can reach up to 60°C, this temperature can only be maintained for a short period. At longer or higher temperatures, the cup may melt slightly.
If you are using a non-automatic heating rod, please pay attention to the heating time. A short heating duration is not a problem and can be reheated. However, using it for too long can damage the masturbation cup, which would be a significant disadvantage!
