WINYI is trying card to create sucking vibrators but they're not really successful at it. They make pussy eating vibrators instead. That's what Sunny is. It works on X2 AAA batteries, is made of ABS plastic and has 10 functions of eating. Imagine getting your clitoris wet with a lube, getting the head of your clitoris into small, round lips that starts spot-on vibration right around the head of your clitoris. As you push it on you, you're gonna feel like a dog is eating you. Even the vibration sounds like an eating dog.
If you're looking for something in a low budget + you're a starter, this is not a bad one to start with.
