(asking the question doesn't sound bad)
To me, they're partially unnecessary and partially ineffective.
Unnecessary because regular cleaning can be accomplished with a simple water + vinegar solution.
When you really need to disinfect, however, they're ineffective due to their format as a wipe.
A spray like F10 would be more effective to cover the nooks and crannies of a cage when disinfection is required (it's also a well known commodity).
