All I can say about this toy is 'Oh My God!'. This toy is just stupid. It is unlike any other vibrating ring you have ever used. It does what all the others do - vibrates externally so it gives great clitoral sensation, but it does what no other ring does, it vibrates the penis. Yes, I'm serious, it vibrates the penis. The shape of this thing makes it so that instead of simply flowing around and around the ring, the vibration is interupted in the ring and moves into the penis. I had this all explained to me before I got it, but I thought they were full of it. I even checked it out with a silicone dildo and could feel that it was vibrating the dildo but I thought it wouldn't do the same thing on a human body. But it really does!
So here's the deal. The vibrating bullet is really strong so you need to be somewhat aroused before you start using it or be someone who likes a strong vibe. It takes a few minutes to get accustomed to it because the strength of that vibe on your clit is all you're going to focus on. but once you get past that, you can feel the internal vibration. It's amazing. It's like a human rabbit habit. If you're partner is skilled with his penis (or if you are skilled at guiding), you can manipulate the internal and the external sensation to get unreal g-spot sensation and just amazing all over stimulation. It's indescribable.
My partner likes it because it holds very firmly at the base of the penis without restricting or scratching. He gets all the benefits of that all-over vibration too.
Some potential drawbacks are that the 4US is very strong. You might be able to put a less intense bullet in it, but the shape of this bullet is unique, I've seen bullets the same width but not the same length, so I don't know if you'd get the same vibration coverage through the toy.
The bullet section is a little hard. There's not much rubber covering the bullet. For some, it might be uncomfortable with too much pressure.
This toy would also be great at the base of a silicone dildo.
4US is made of Intramed which is a new material that has all of the same properties as 100% silicone (as it says on the box). It's waterproof and very easy to clean.
