The 12 programs can be controlled via the intuitive one-touch button. Since the Satisfyer Game Changer is waterproof (IPX7), it can also be used in the shower or bathtub. Furthermore, its exterior is made of body-friendly silicone and can be cleaned with warm water and mild soap. If the anal plug ever runs out of steam, the integrated batteries can be recharged with the included USB charging cable. The anal vibrators in the Satisfyer Plug Vibrator series come in a variety of shapes, are a manageable size and are easy to use. This makes them really great for anal play newbies. We always recommend the use of a water-based lubricant for smooth pleasure.
