Why is "The Curve" cb used by so few people?

I use the curve cb (A.L. Miller Enterprises) and have been enjoying it for the last week or so. Why is it that so few people seem to use it? Just curiosity here.

It is too big for most. Welcome to the forum.

Bulky, unwieldy, and doesn't hide well under your pants.

I think most of us would have to much room in the Curve and it would not feel like one is wearing a chastity device.
