When comparing high-end and low-end sex dolls, the differences primarily lie in material quality, realism, durability, and features. While both types serve the same basic function, high-end dolls are designed for a more realistic, immersive experience and come with a significantly higher price tag.

Material quality is one of the most noticeable differences. High-end dolls are typically made from premium silicone or high-grade TPE, both of which are durable, non-porous, and feel more like human skin. Low-end dolls, on the other hand, are often made from cheaper, less flexible materials that may wear down quicker or feel less lifelike. Silicone dolls in particular offer a firmer, more realistic feel, while TPE is softer but requires more maintenance.

Realism is another key factor. High-end dolls feature lifelike facial features, body proportions, and skin textures. The details, such as hand-painted skin, veins, and hair implantation, give these dolls a more human-like appearance. Low-end dolls tend to have simpler designs and less attention to detail, resulting in a less realistic appearance overall.

Internal skeletons in high-end dolls are highly articulated, allowing for natural movement and posing. These dolls can bend, twist, and hold a variety of positions with ease. Low-end dolls may have less flexible skeletons, making them difficult to pose and more rigid in movement.

Lastly, durability and maintenance are key differences. High-end dolls are built to last longer and maintain their appearance over time. They are easier to clean and more resistant to damage. Low-end dolls, however, may require more frequent repairs and can wear out faster.

In conclusion, the primary differences between high-end and low-end sex dolls are in the quality of materials, realism, articulation, and durability. While low-end dolls can still offer enjoyment, high-end dolls provide a more realistic, long-lasting experience.
