The F1 is like no other sexual product for men. Instead of focusing on the nerve endings on the surface of the penis like most traditional products and sexual acts, the F1 also uses SenSonic technology which emits sonic waves to stimulate the nerves from within. This creates a different type of amazing stimulation that will blow your mind and your load time and time again. The F1 is controlled via Bluetooth through an app or by controls on the device. They also offer a demo app that you can test out to get a good idea of what you can expect before making a purchase. As for quality, this product is superb, using a premium textured aluminum body and silicone interior. There is no stroking required with this product. This means your brain can 100% focus on receiving pleasure, no distractions from the nerve endings in your hands, the feeling of your arm moving, it's like someone else doing everything for you.
