What kind of female sex tool is better? Who can recommend it?

Female sex tools: I recommend you to use Japanese Darth Vader massage. Female sex tools can increase endocrine, enhance sexual pleasure and increase the intensity of lumbosacral nerve reflex. I bought this Japanese Darth Vader massage stick, which cost more than 400 yuan. It has been used for more than a year, and there is still no problem. This Japanese product is better than that made in China.
