I love this thing; my girlfriend and I bought two of them, and they're our primary vibrators. I often use it for external stimulation. The bulb doesn't give at all and is very hard. For me and my girlfriend, it's generally too hard and big for insertion. I can't speak for other people though.

For the most part, I like this toy because of the crazy vibrating power and the round shape of it. Level 3 vibrates so hard that it never fails to get me to orgasm...if I can handle it. Definitely not something you could start out on. Even level 2 is pretty strong and is usually more than enough. This is the perfect toy for someone who has difficulty orgasming. And if that's too much, you can always go on level 1, which is pretty low key and comfortable. Unfortunately, levels 2 and up (sometimes even level 1 if the walls are thin or the door poorly insulated) can be heard through closed doors.

It's great for masturbation. The shape of the bulb is perfect to rub against, and the fact that the neck is bendable makes holding it a lot less awkward. Though it is worth noting the rod doesn't completely hold its shape when pressure is applied. It doesn't give by very much though. While males can certainly use it, I'd suggest they buy another type of vibrator. Every now and again, I use it during foreplay; it feels good on the nipples and inner thigh. Also, the bulb is large enough for two women to rub against it at once. If you can manage it, hold it between you and your lover while you scissor.

It's easy to clean and rarely gets "dirty." I've had the toy for over 2 years, and it still works perfectly. However, it is kind of annoying how quickly it goes through batteries.
