Not bad, but there are better gums than this one. At the beginning is a big explosion of flavor and sugar like sensation, but after 5 minutes is gone.

Ex Input:
The Melitta Java Pods Have a slightly smaller circumference than the Senseo pods and are thicker. If you are using a Senseo coffee machine, you probably should moisten the Java pod and smooth it before attempting to latch the lid. Otherwise, you risk breaking the latching mechanism. The resulting decaf coffee is not bad and seems to this reviewer to have a richer taste than the Senseo decaf pods. The Melitta Java pods are not really designed for the Senseo machine and several other brands such as Halo, Fratello and Millstone work better in the Senseo machine.

I shared these with my two older sons, then ordered more. These are great to put in the glove compartment for after work.
