Having read about the 24 hour supermarket machine, we just had to try it out for ourselves.
The menu was easy to operate, and our purchase was delivered quickly. But I had a feeling, that the 2000 items had been selected to give a wide variety of types of item, rather than trying to offer different brands of the same item.

This is obviously an attraction for those who have left something at home, a toothbrush, for example, and are happy to have any type as long as it’s available any time of the day or night.
Since there is a normal type of supermarket in Puerto del Carmen next to the machine, anyone wanting something more specific may need to go there during opening hours instead.
