With Satisfyer's new app-controlled clitoral vibrator, you now have endless combinations of pressure belt stimulation and classic vibrations. Of course, the vibrator can also be used without the app. For even more pleasure, you can use water-based lubricant for an even more pleasurable experience. To preserve the silky smooth silicone surface, avoid using silicone-based lubes. In addition, the vibrator is waterproof which makes the product easy to clean.InformationBrand: SatisfyerSeries: Air Pulse Stimulator + VibrationModel: Curvy2+Type: VibratorColour: PinkMaterial: Silicone & ABS Vibration range: 10Waterproof: Yes (IPX7)Battery: Rechargeable Li-Ion batteryCharger included: YesCharger type: USBBluetooth: YesApp: YesSize: 13 4 x 4 5 x 10 3 cm Weight: 121 g
