Best Double Balloon Retention nozzle

I'm hesitating between two models. I want it to seal very well.

The only manufacturer of good nozzle is medtech3000. As I found these two models on their website.

I want to ask which of the two I should choose

The first one is the classic one I've seen it on many videos and also many people leak water with it. There is a big gap between the two balloons that i don't like and i think will cause leak.

The second one is more rare and not so popular but never saw leak with it.

I have used the second one (Ruesch nach Gaul) for many years and can recommend it. I haven’t used the first one.

N.B. You can still have leakage, depending on how tightly you inflate the balloons.

I have both of these nozzles and I agree with you about the space between the balloons with the original poplar design but if your willing to inflate the balloons a bit bigger than they are designed to be then it won’t leak or be able to be pushed out! The softer balloons sort of conform to your body and feel very comfortable. I know that treating this nozzle in this fashion will result in a rupture eventually but I’ve been having fun with it occasionally for a few years and so far so good! I have even ordered a second one just in case! Now the other nozzle is an “I mean business “ type of device. The balloons are a different type of rubber that holds the sphere shape very well these balloons really put pressure on your ass to make sure that you can’t expel! This is my go to nozzle! I simply love it!!! It controls my asshole! This nozzle can take a beating for a long time! I over inflate it all the time and even at that it still works and I have had it for years now! It takes about 10 pumps to make it very hard to push out at 15 pumps for me it will make it impossible to push it out!!! And as the 3 quart bag is finishing I am jerking my self off I will then pump 4or 5 more pumps in and the discomfort of that huge balloon plus the 3 quarts makes me cum hard!! But as soon as I get off I have to deflate it because it’s so uncomfortable it’s slightly painful.So much FUN!!! So if you want a softer feel and more relaxed fit the traditional way is the way to go but if you want a nozzle that commands your ass then the yellow and red one is the one you want!!!

Mine is silicone 750. Inside, 300 outside works great, easy to insert too

The second one is my favorite. Insert both balloons and no leaks. Also feels incredible!!
