If you are on the lookout for some smart space saving kitchen appliances, you might love to consider the Compact4All, from the house of Dutch electrical goods specialist Princess. Princess has teamed up with Jan des Bouvrie to come up with the Compact4All, a stackable set of four kitchen appliances – kettle, coffee maker, toaster and a squeezer. All the four appliances can be used individually and when placed as a set, they can function with one central outlet.
