A very high percentage of posters on here are infatuated with them. When I used to use melamine I'd use them as it would act as a backer of sorts and prevent some chipping. Now the only time I use one is when I'm making drawers I cut a 1/4" off of each edge to remove the tearout from the router bit, and its nice having the drop just sling off of the table rather than dive into the saw cabinet. Other then those two things, whats the point?

Or am I missing something?.....
