I know one thing, this one stands out from the rest. Very unique design and fabulous feeling. This one gets the job done whether being used solo or as a couple. It can be used on a male or female. This octopus‑inspired design is very unique and is what makes it different. The round rotating head is a game changer and definitely a BIG plus. It heightens levels you may never thought you would experience. The 10 vibration levels with powerful motors and rotating head offers variety of different preferences and effectiveness. The remote control is easy to use and very convenient. The silicone material feels soft, safe, and skin‑friendly. Again this is versatile for man or woman. Comes with magnetic USB charging cable. As well as comes in a discreet packing which I love. Explore the difference!
