I love how the mouth and toungue are bigger/wider than other toys ive used and the tongue moves in so many different speeds and patterns it almost literally feels like its real. You can also use the vibration along with the tongue motion to make things even more intense. The vibration also has many speeds and patterns. If i need to climax fast, this amazing toy gets the job done in about 4 mins with both functions. If i want a slower climax i just skip the vibration and enjoy the soft perfect motions of the tongue.Another perk is how perfect it fits into my hand and very easg to hold with its unique design.So far ive only had to charge it the first time after opening the package and already used it 4 times in the last week.The satisfyer used to be my favorite toy but this one is hands down the best and most satisfying ive ever had between my legs ;)Highly recommended.
