This toy is 2 pieces, and the jelly attachment is FORTUNATELY optional.
You have a battery pack/controller that is wired to the bullet and the jelly skin that is molded to look like a tongue and lips. The vibrator is controlled via the handheld battery pack and dial. This toy is thankfully fairly conservative with the two AA batteries that it uses.

First, I think the description is actually a bit misleading. The description says "..You can set it to simulate licking and flicking on the control dial..". The tongue does not actually flick or lick on it's own. This would have to be done manually. Also, because of the thickness, and stiffness of the jelly material and the length of the lips and tongue, very few vibrations make it to the tip of the tongue nor provide any noticeable stimulation. Not to mention cleaning is a bit of a hassle. It can be difficult to clean at the base of the tongue inside of the jelly pseudo-mouth. The lips are fairly stiff and hard to move around to clean the toy thoroughly.

Using this toy with the provided tongue and lips skin just honestly feels downright awkward. Even when desperately flicking this clumsy jelly tongue against my clit, it just nothing for me. All you feel is that jelly tongue. No vibrations to speak of. I suppose this could be good for a warm up or foreplay with a significant other, or just for teasing.

The toy becomes a bit more interesting once you remove the jelly skin and use the egg/bullet vibrator by it's self. However, it's vibrations are lacking for me. This may be in part because I tend to prefer a stronger clitoral vibration to get off. This may be perfect for someone who likes to take their time building up to an orgasm, it's just not for me.
