I mainly use netcut to prevent access to others when playing online game or when relatives share the wifi password to abusive neighbors who by then will share it to others. Removing access from many different users isn’t a problem since there is a “brand” label which will narrow down the choices and the most common brand in my case is samsung and apple. Also netcut UI not only shows IP address but also MAC which is helpful when marking that particular device who is troublesome.
Problem encountered: The slider which I think is supposed to how much allocation that device will have is not working. When you remove 1 bar it will still totally remove access(I don’t know the slider option is for pro only).
Nonetheless netcut is a very useful tool and it’s free which gives us the idea how reliable it is.

I mainly use opera browser but all of my browsers installed are working fine with netcut.
