Brand, material, model, size, details … these are not the criteria that guide your selection. The most important thing is to find a reliable sex doll seller and understand everything related to dolls (including essential maintenance), but for others, trust your instincts and make your heart sound. If the doll meets your expectations in practice, then technical aspects will constitute auxiliary data. But there, only the future can confirm it to you. For silicone dolls, there is no problem, they are almost all sold by the manufacturer (or official importer). Beware of TPE! In my case, if I had to buy a sex dolls, I would not hesitate to find a serious seller here.
