Above all you should consider how to use the power socket!
- There is a device permanently plugged (eg radio / television ...)
Then, such a fuse is very useful. You hardly disturbs (because you never set about).
The child can also pull the plug without any problems and would have a power outlet (and probably still the device-jack for poking). Since the twist mechanism helps well.
- One to a socket, you need rare times
Then this backup is also very useful. You need only every few days, they hardly interfere.
And because it is rarely charged, it breaks little.
- An outlet that you need and set about constantly (eg dust Auer, mobile phone charger, hand blender in the kitchen ...)
Here is this rotation system, at least these parental controls not quite optimal.
Firstly, it is quite hakelig (if you turn with only one contact, it stuck like)
On the other hand, you can, if the contacts are not perfectly straight or be pulled tilted even slightly pull out this fuse directly. Rather susceptible. To this end, there's the one star deducted.
We most outlets fall into the first two categories, and maybe 4-5 outlets for vacuum cleaning etc. in the final. Here, then worth more expensive but more robust for it.
Overall, for the price so OK and therefore 4 stars.
