There is a reason some sensations stay with you. The Thump It does not vibrate in the traditional sense. It thumps. A weighted internal mechanism creates a deep, rhythmic pulsing that you feel from the inside out, and once you understand the difference, standard toys start to feel like a step down.The curved silicone shape is designed to position that thumping action right where it counts. Premium silicone means the surface is smooth, flexible, and comfortable for extended sessions. Seven functions across four patterns and three speeds means you are not stuck with one setting until you find the one that works for you, and then you will know it immediately. The remote control keeps your hands free and your focus where it belongs. Rechargeable means you grab it when you want it, not when you remember to change batteries.At 4.5 inches of insertable length and a comfortable 1.65-inch diameter, this is a toy that delivers serious internal stimulation without asking you to work up to it for months. If you have been curious about internal play and want to start with something that actually does something, this is the one to start with. No guesswork. Just buy it.Product DetailsOverall Length: 5.3 inches (13.46 cm)Insertable Length: 4.5 inches (11.43 cm)Diameter: 1.65 inches (4.191 cm)Total Functions: 7Vibration Patterns: 4Speeds: 3Power: Rechargeable (plug), remote control requires 2 AAA batteries (not included)Material: Silicone and ABS
