These disposable grease cup liners are a must.  No sense in spending unnecessary time in clean up.  The way the griddle is made, you can scrape the crumbs and the grease into a crevasse in the top middle of the grill to get it off of your cooking area and it goes straight into the liner.  Well worth their money! I like the fact that they come in a large quantity.  As much as we use our griddle, it really adds to the convenience and value of the griddle!
