This repeater is quite efficient, it allows a better efficiency in Wi-Fi network in your home.
Indeed, some of the walls can sometimes prevent good reception so this repeater is there to improve this stuff.
If you follow the instructions in the manual, your accessory will be operational quickly.
The box is small but still encumbers an outlet, after all depends on your installation.
This repeater fulfills its function so I recommend this product.
Sincerely.
