Does what I ask of it
I often need to know if an unresponsive device on my network is connected or if it had dropped off. Fing never has failed to detect a connected device, which allows me to determine if it is disconnected or merely unresponsive and to ping the device. I know I am just scratching its surface and that it is a lot more powerful than I can appreciate, but, for my purposes, it just works.
