These are tasty, with a nice buttery flavor.  You do not need to add butter or milk, just add hot water, which is the original reason I bought this flavor.  I bought them for camping, but like them so much I keep some in my pantry.  I work long hours so I appreciate short cut foods that taste good.  This is an example of that.  Sometimes I mix this with plain Idahoan mashed potatoes to change the flavor, it is all good.
