So far after a week in this cage its been very comfortable. Even with the reduced length compared to the my last one. The manufacturer is probably not raycity but that's how I purchased it off amazon. There are several other spots you can find this one. I ordered this one after my last one started to pinch and instated to get hot spots from wearing between the bars ( and i could easily touch my little thing, I know, bad sissy ). Even from the first minute input it on I felt so much more secure. VERY little skin can be touched through the tightness of the bars. Pros Tight bars Easy to put on Comes with catheter (see con as well) Comfortable Stainless steel Low cost Choice of ring size Cons Sharp top on lock(easily ground down) Same keyway as other integrated locks Catheter just too long (sits just in the wrong spot but can be cut and super glued) Interesting tidbit/warning If not using the Cath and your foreskin is just sitting wrong and the holes aren't lined up right, peeing can be VERY messy, however it feels amazing as your foreskin fills up then dribbles down your sack. Have not been milked/orgasmed in this cage and I think it would be a most incredible feeling as you com into your foreskin. Excerpt from amazon Features: This item is made of stainless steel.
