full metal device from China.

I have got it (Chinese version). Don't know if review here is the right place. The tube is pressed between your testes. They bulg out. I have a rather short one (to my humble opinion) so the glans is pressed firmly against the exit hole. The rather width, anatomical, ring is actually very comfortable ( I do not mean the distance between the tube and the ring, but the ring itself). So in my experience it is very restrictive but I can't waire it 24/7. After 1 or 2 days i want to get out to clean an get some space. Hardons, and semi hardons tend to press the device away from the body and hurt the balls. So the device is still in my 'in use box'.
Cheers!

 

I have that one . It's a metal version of a plastic device I like . The plastic is light weight and fits perfectly but being plastic it needs removing for cleaning every couple of days .
This is comfortable for me but just too bloody heavy . The base ring fits well and is smooth but the cage is too closed so again has hygiene issues if on for more than a few days . Also connection between base ring and cage is a bit loose so can pinch a bit . It you are starting out the plastic version is so much better . Any full metal cage from China is just too heavy to wear , I have 4-5 and none are suitable for long term if that's what you are after .
