Cheaper parental controls are better.

1. reer 3246,020 - Steckdosenschutz white, 20 pieces for 5,50
2. 10 x Child Protection Parental Control for sockets with twist mechanism of goodbay for 4.64
3. Wentronic child protection for plug doses 5 pieces per set for 1.33

Price comparison:
The price comparison Wentronic win (26.6 cents / unit) before the REER (27.5 cents / unit) and the goodbay (46.4 cents / unit).
Oddly, the child protection from Wentronic is identical to the figure of goodbay, whereas those of goodbay is no logo in the middle.

Practice:
I would recommend to stay away from the REER Electrical Outlet Cover. From our 20 most connected not again after the connector has been removed. The problem had neither the children nor the protection of Wentronic of goodbay; both close reliably with us.
The Drescheibe inside the socket protectors is much thinner than the other two products, thereby having the disc game and gets stuck in the pass.

When inserting a plug the reer Steckdosenschutz are also exasperating. The connections on plug our Toasters include further apart than the extinguisher in Steckdosenschutz. The turning is difficult, the connector slides off repeatedly. Needless some practice to be able to plug in devices quickly. Unfortunately, two of the outlet plates were out pulling the plug hang at. That seems to happen with plug power supplies like, damanche Front at the contacts are wider than later.

We have the impression that it was at this Steckdosenschutz a cheap copy of a thoughtful product.

Conclusion:
Now that we have tested these three products we are secure because of the good value for money, most of our sockets with child protection from Wentronic. A little luxury we afford but, order addition another 10 pieces of child safety goodbay for frequently used sockets.
