I was hoping this toy would be great for my finicky anatomy and troublesome finger joints, due to its shape and size. Unfortunately, it's just not enough to get me where I want to go. The size is a little small for my hands, which means my fingers are more curled than I'd like, and the vibrations are just insufficiently stimulating. I haven't had any trouble with the charging (yet), and the toy is fun as part of other activities, but for solo play, it's not worth it. My $35 winged vibe is only slightly worse for my hands, and much better for my bits.
