These are probably real switches. Home switches lack managibility and such, while this unit will probably allow you to select exactly what speed you want a specific port to run at, see complete traffic statistics, and more. Based on the "SuperStack" name, it probably also work well when used with a second switch of the same type, where they can be bound togther to work as one.

It should work fine as a normal switch at home as well. Benefits of these devices aren't really aparent except on large networks though.
