After my other half has had so much fun teasing and toying with me in public, when I saw this, I knew the tables were about to be turned. App controlled with 9 vibration modes, she has never gone out of the house to go to work with this in and not made sure to let me know and I've not jumped at the opportunity to electrify her day. Extremely quiet in hand it's absolutely silent when she has it in that regardless of if she's st the store or at work in a meeting, this is one of those true pleasures she has with me when we're not together. Made of a very soft silky feeling silicone, she says it is absolutely comfortable to use, large enough in design to not only ride on her G-spot, but to also not be uncomfortable to insert. Its battery charge lasts for a while, and it's never lost contact with the app regardless of what she's wearing.
