The moment she settles in and lets it move, she will understand what all the thought behind this purchase was for. The Bi Stronic Arc does not just vibrate. It pulses and thrusts on its own, finding the rhythm so she does not have to. Her G-spot and clit receive simultaneous attention, and when both hit at once in exactly the right way, what follows is the kind of full-body orgasm that builds slowly and lands hard. She just has to hold on.Fun Factory engineered this with 8 thrusting programs and 6 vibration programs, which means she can start soft, build gradually, and lock in the precise combination that takes her exactly where she needs to go. The ergonomic loop handle gives her a secure grip no matter how far gone she gets. USB-C recharging means it is ready when she is, and the IPX7 waterproof rating means the bath, the shower, or anywhere else is absolutely on the table.You put real thought into this and it shows. The Bi Stronic Arc is not a compromise. It is one of the more sophisticated pieces of engineering in this category, and she is going to feel every bit of that the first time she uses it. This is the kind of gift that gets remembered.Overall Length: 8.78 inchesWidth: 3.11 inchesThrusting Programs: 8Vibration Programs: 6Material: Body-safe siliconePower: USB-C rechargeableWaterproof: IPX7
