Top cage choice for staying put during erections

Hi there! I’m currently using a knock-off HolyTrainer v4, but whenever I get an erection, it tends to slide up and pull on my scrotum. To manage this, I’ve switched to the second-smallest ring size because the tiniest one feels too constricting.

I’ve been pondering this issue for a while now and would appreciate any advice from you all. Someone mentioned that an anatomical ring design might be part of the solution, but I’m hesitant; I’m not certain if switching to a device with a rounder ring shape will actually help me.

Additionally, I’d like to give a plastic 3D-printed cage a try and have narrowed it down to two options: Cobra featuring a simple ring ( And a newer model that sports an innovative ring design (

Which of these do you recommend? My plan is to start with the affordable knock-off version from AliExpress, and once I’m happy, purchase the authentic original.
