Overall, this isn't a bad product. The main problem I've had is with the bullet shorting out. This is fairly common of cheaper bullets; the more wires, the more likely it is to have issues (at least in my experience).
However, the flip side of this is that the cover (which is the best part in my opinion) is removable, so it can be put on other bullets (or even onto a smaller dildo or other vibrator). I just moved it to a bullet that doesn't have a wire. But when the bullet is working, it's a nice little toy. Pretty good vibes. Not the strongest I've tried, not the weakest.

My girlfriend loves to be teased with this. I usually have to use something else after it though because while the ticklers are very nice, and tease her, she doesn't like the way it feels when I press it hard enough against her for her to orgasm. So while I'm sure some people could finish with this, that hasn't been my experience with her. I've used it limitedly on myself, and I like it, but I think I'm a little too ticklish for it, so I usually stick to using it on my girlfriend.

Clean up is tricky with this. It's definitely my least favorite toy to clean. There are so many crevices and individual ticklers that it takes time to clean, and if you don't clean it right away, then it becomes even more of a hassle if there's dried gunk on it. But at least it can be removed to be put under a stream of water. If it was attached to the non-water-proof bullet, it would be a complete pain.

Again, it's not terrible, but for the price, I have other toys that can make me finish more easily and that are easier to clean.
