It is more cost-effective to buy a basic flat chested sex doll at a low price and then add modules later. For example, if you buy a second-hand model for $800 and then spend $300 to upgrade to the latest AI chip, the total cost is 52% lower than buying a smart model directly. The skeleton of a life size sex doll can also be strengthened: the carbon fiber joint kit ($85) can extend the service life by 3 times. |
