1.Material: Is the material of the sex doll TPE or silicone?

TPE (thermoplastic elastomer)
Advantages: soft, good touch, low price
Disadvantages: easy to get dusty, need frequent maintenance, general durability

Silicone
Advantages: more durable, clearer details, anti-aging, makeup is not easy to fall off
Disadvantages: high price, slightly hard feel

The first step to judge the value: the higher the material and the better the stability, the higher the price.

2.Is the skeleton structure flexible? Can it be in various postures?

High-end Sexpuppe use metal skeleton + multi-joint movable design, which can complete various postures such as sitting, lying, kneeling, standing, etc. Some also have simulated human skeletons, such as neck, fingers, and toes with higher mobility. Entry-level Liebespuppen often have simple skeletons and limited postures. The flexibility of the skeleton is equal to the practical experience value and one of the keys to the value.

3.How is the detail craftsmanship and simulation degree?

Is the skin texture of the Fanreal Doll natural? Are there any vascular lines or pore details? Are the facial features delicate and symmetrical? Are the hair, nails, and eyelashes implanted by hand? Is it firmly fixed? Is the makeup long-lasting? Is it convenient to reapply makeup after removing it? The more delicate the craftsmanship, the more real the sexdoll is, and the higher the value.

4.Are there AI functions or interactive technology?

Modern high-end Real Lady have added a lot of black technology:
AI voice interaction: can talk, call your name, and respond to emotions
Body temperature heating system: simulate real temperature (usually around 37°C)
Vibration/sucking function: increase pleasure experience in specific parts
Bluetooth/APP connection: customizable settings or remote interaction
Technology means added value increase, which means price increase, but the experience improvement is also obvious.

5.Degree of customizability

Advanced brands support customization: face shape, hair color, skin color, height, bust, vagina type, voice, etc. are all optional. Some can also choose real person imitation service (customize the appearance of the doll according to the photo)! Haute couture equals a distinguished experience, which naturally also means higher value.

6.Brand and after-sales service

Big brands are usually more mature and reliable in:
Safety and environmental protection (non-toxic materials)
After-sales guarantee (such as damage warranty)
Transportation packaging (privacy, pressure resistance)
Instructions for use (maintenance, cleaning guidance)
Don't ignore the service value! A trustworthy brand is often worth the money.

It looks like a simple Lusandy Doll, but in fact it is a combination of technology, art, and emotional experience. If you are buying it for the first time, it is recommended to clarify your budget, purpose and preferences first, and then measure the cost performance based on the above points.
