Question about the ring sizes

From their website:
diameters available :

• 36mm (1.41inch)
• 40mm (1.55inch)
• 45mm (1.75inch)
• 50mm (1.95inch)
• 55mm (2.14inch)

Those are inside diameter

 

Measure them across the widest part of the ring.

 

There should be a number on the inner part of the ring believe 0 is the smallest and 5 the biggest

 

I got my nub last Friday. I measured per the website and found that the standard 45mm should work. In reality, the 45 is too small for me. The problem is the space between the tube and the ring is not wide enough. I ordered a 50mm and it should be here Wednesday or Thursday.

 

I measured the rings and the actual is from inside to inside from top to bottom.

 

Hi there...

If the above list is correct, stack them up and look for the smallest one!!!

Kindest regards.

I have an HT2 aswell. Acording to the table on the official webpage i should use the largest ring. I swap between the largest and the second largest ring and can't decide which one i should use. The smaller ring fits really nice but also quite tight. The larger ring is not ns tight but makes it possible for the cage to slide further down my shaft stretching my scrotum quite a bit more than the smaller ring.

What are your experiences and recomandations?
