We-Vibe Sync O Remote and App Controlled Rechargeable Couple's Vibrator

The remote control works well even through walls, which is handy when your partner is in another room. Battery life lasted through a whole evening of play without needing a recharge.

The app connectivity is surprisingly intuitive and let us both control the intensity from across the room. It fits comfortably during use without slipping out, and the remote is a great backup when we don't want phones involved.
