It depends on the state of my skin.
When my skin was irritated and weepy, the wafer's adhesives alone didn't feel secure. The belt helped there, although I don't know if it actually helped much or just made me feel better about it.
Now that my skin is doing well, I don't use one. Everything feels very secure, so I feel fine without.
The belt is vital to the adhesiveless system that I had to use for awhile while my skin was healing up.
