This product is beyond simple to use i received the Keurig a carrousel & an assortment of coffees and teas. Once i had unboxed the Keurig it was smooth sailing our fresh water in the top up to 10 oz, insert Kcup close Kcup lid allow time for water to drain into the brew tank & in less than a minute you have a delicious hot beverage. Best thing I've received for review. "I received these products complimentary from Influenster for testing purposes."
