Promising review: "This toy is small but mighty! I was quite shocked by how tiny it is, but it definitely doesn't skimp on sensations! I've tried this toy on every setting and I have to say there isn't a single one that I don't like! The first, slower setting mimics exactly the kind of oral I personally like, and is definitely one for those who like to take it slow and be teased. The faster continuous settings also feel amazing, especially when moving the toy ever so slightly from side to side. They definitely manage to bring me close to orgasm much quicker! However, the last couple of settings are personally my favorite, giving you a variety of sensations, both fast and slow. I found these settings to be the closest to real oral and they definitely brought me to several amazing orgasms! The trick with this is not to use too much pressure and to allow the tongues to gently flick across the clitoris. Less is definitely more with this toy! The silicone tongues are super soft and I didn't find them too difficult to clean, especially since it's waterproof! I can't wait to try this out in the shower! It's not too loud, even on the faster, more powerful settings, and it's whisper quiet on the slower ones. It's already up there with my favorite toys!" —Kitten25
