Customized features and heating systems: Sex dolls from different manufacturers may have different customized features and heating systems. Some manufacturers may offer more advanced heating systems to increase the realism and comfort of their sex dolls.

Doll Models and Materials: Sex dolls from different manufacturers may be made from different models and materials. Some manufacturers may pay more attention to the realism and detail of the model, using high-quality silicone or thermoplastic elastomer (TPE) materials to make the dolls to provide a more realistic look and feel.

Height, body shape, and selling price: Sex dolls can also vary in height, body shape, and selling price. Some manufacturers may offer options in different heights and body shapes to meet the individual needs of users. At the same time, the selling price of the doll will also vary depending on the manufacturer, material and degree of customization.

After-sales service and guarantee: Large manufacturers usually provide more reliable after-sales service and guarantee. They may offer a longer warranty or more comprehensive after-sales support, giving users more confidence in buying and using sex dolls.

Split sales and discounts: Some manufacturers may allow sex dolls to be sold separately, such as selling the head or torso parts of the sex doll separately. In addition, large manufacturers usually provide discounts and promotions to provide users with more competitive prices.
For example, some customers just want to buy some sex doll heads, then some manufacturers will customize them individually according to the customer's requirements, or some sex doll torsos, and the price is very cheap and the arrival time will be very fast.

In general, sex dolls from different manufacturers may have differences in design, materials, customization functions, selling prices, and after-sales services. When choosing a doll, users should choose the appropriate manufacturer and product based on their own needs and budget.
