This unit is very easy to use. It tells you when to add water, raise lid and add water. It tells you when it is ready for use and the next cup. Blinks for you to select which size drink you would like and tells time and more! When using the k-cups it punctures two holes in the cup but it does not drip when you remove from the unit to dispose. I turn my unit off and unplug after each use. It states in the manual that it vibrates which is true but it doesn't tell you how loud it is! I also noticed that the menu/clock area gets a bit warm to the touch without brewing. I haven't left my unit...
