no brainer - save time and money By crackischeaper on 6/18/2014crackischeaper would recommend this product to a friend-Save money by buying your media in larger quantity and fill all your cartridges at once.
-Cut your maintenance time in half by having one of these (or more) ready to swap out as needed.
