I liked the design because it did feel good in my ass. The tapered tip and the bulb held it in place, which is good. It didnt feel huge, but it was enough to make me aware it was there. As for the vibration, its more of an angry buzz. Not to mention the package says multi speed, which it isn't. The bullet runs on 3 "cell" batteries which are about the size of your pinky. So even though its about a 2 or almost a 3 on the simulation level, the batteries die quickly. As for the size of it, the total length is 3 1/2", 2 1/4" insertable, and an 1" wide at its widest insertable point. I say get another mini bullet and replace it. So overall, replacing the mini bullet here or even removing it all together makes this a great starter toy.
