They work fine until they - well - until they fail.

The cheap hubs are not worth trying to do anything with.  If a port
fails it often gives no indication except loss of connectivity
(sonetimes a loss of link light, and sometimes not).

AFAIK the cheaper ones are not manageable, and do nothing intelligent
but autosense connections and perform switching.  When they fail, they
are toast.

If you want the ability to manage a switch they are often several
hundred $ in cost.
