The Neo is perfect for those looking for a vibrating ring with a more compact vibe. Neo is made a very stretchy elastomer to fit almost any size. The vibrator is thick enough to feel and to bridge the distance between partners but not so wide as to be uncomfortable. Neo has two settings - continuous vibration, or vibration on contact. The LR54 batteries are replaceable (2 sets included). Made of soft elastomer. by Vibratex. Neo comes in its own storage box.
