It was purchased to monitor the use of the child's computer (PC). The first negative flaw, and a very serious one, is the lack of hooks for attachment in the recessed wall box. You will need to come up with a workaround in order for the socket to stay in the right position, and it is doubtful if it will remain in place when you unplug the plug.
The connection was somewhat difficult as you will need to press the WPS/Pairing button on your modem/router during the device detection process. An action that is not mentioned anywhere in the manual!!!
The third negative is the presence of an ON/OFF button, even though it is stated in the specifications that it does not have one!!!
The Blitzwolf app is great and I had no trouble making any adjustments I wanted.
I will come back after a while once I have gained some experience with this smart socket.

It loses one star because it doesn't have "hooks" to hang on the wall, so the problem was solved with silicone!! It works perfectly, connects seamlessly and quickly, and does what you ask of it. I don't know about surge protection, and to be honest, I don't want to know
