- Looks good
- Simplifies life
- Easy in any outlet and you've got 3 terminals without a lot of cables, etc., fine.
Negatives:
- The socket connections are quite hard to use, ie plug the go will be introduced only "hard" pure and accordingly out again.
(But does not bother me, because anyway always all plugs in it.)
- The grounding plug should be turned by 45 degrees! Hidden a Euro plug, when the protective connector is at right angles
