@Limpopo, If you are new to making espresso, buying an espresso pod machine is a good option. Espresso pods can be used in espresso pod coffee makers as well as pod compatible espresso machines.
Using the pods is quicker and easier, since you will not have to measure the espresso out. Sometimes packing the espresso can lead to variations in flavor, if the espresso is packed too tightly or loosely. The pods are pre-packed and just right, so your shots will be consistently tasty.
