Positioned to repeat my wifi signal in our room, this repeater works well. It is however very sensitive to variations in the signal and can switch from green to red and then orange and then back to red and green all in 5 minutes. But the configuration is very easy and it does the job. In addition with a plug, this avoids to condemn.
And for information, it must be fully seated in the socket, which requires pushing a little. But it has the merit that it does not move every time you remove the plug of the equipment we plugged it. A very good point!
