Difficulties with wearing a device? discussion

With a 45 mm ring and 15 mm spacer, the pressure can sometimes cause part of the ball to slip through. Switching to the next smaller ring fixes this issue, though it feels slightly snug. However, reducing another step in spacer size also results in a tight fit when paired with that same 45 mm ring. So, I’m wondering whether I should opt for a tighter spacer or if the current 45 mm ring is simply too loose.
