Elva has SVAKOM Intelligent Mode which highly imitates the vibration frequency in the whole process of sex from the beginning to orgasm. Single-click the S button, and you can start an incredible sex journey. From bashful foreplay, sexy teasing, and strong pulsing, to multiple climaxes, it's a heavenly sex experience you don't want to miss. Elva can be used with and without the remote control. With the remote control, this will increase the interaction between you and your partner. Elva has been added a string at the top, which is made for easy removal after using it. The amazing thing is that it is also an antenna for receiving orders/signals sent from the remote control. Elva is splashproof at the IPX6 level. IPX6 Waterproof means Elva is protected from powerful water jets.
