This set is perfect for me and my wife. We have different preferences and this device allows us to make two cups of fresh veg and fruit mixes. The cups are well designed and constructed. Its cover seals very well so you can carry it in a bag to bring it to drink at work. The insulation of the cup is so good that the juice inside will not be cooled much if the cup is put in a refrigerator. This made it undesirable for my daughter who likes super cold juice.
