MATERIAL: Petting Hippo is made from silicone and ABS. It is compatible with water-based lubricant. It is waterproof so you can enjoy the hippotastic moments in the bath or the shower. STRENGTH OF VIBRATION: Deep. rumbly and satisfyingly strong. There are 12 different vibration patterns to enjoy. NOISE LEVEL: Nothing scandalous. USABILITY: Very intuitive. Thanks to its looped handle. it is very ergonomic to hold. A full charge takes 3.5 hours and that will provide you with approximately 50 minutes of pleasure. The buttons are very intuitive. A power button and 4 circles to increase the intensity and 2 circles to go back to a previous setting. ORGASM-O-BILITY: OMG!!! Thanks to my detailed fantasies about yoni gazing and pussy worship. Petting Hippo has made me orgasmic on many different occasions. This shape is unusual and I LOVE it. Not only because it's a nose. but also because it is highly effective.
