Not so good!
The description gives a laundry list of what it can do but fails to mention what it cant do. It does not list all devices on the network. It does not work well with all routers and switches. It could not identify the name and status of known apple devices. Most features only work with Apple AirPort or Bonjour. I have IP Scanner and that program does show all devices and correctly identifies them. iNet may work better with Apple AirPort but failed miserably with Netgear. I had nine devices on the LAN and iNet only ID six, two they listed as "Host is hidden" with the "Online status uncertain". Two PC devices were totally missed. IMHO there are better net scanners besides this one.
