Pros - Small size fits in pocket/bag for light tools. Powered by 2 AA or POE batteries. Front panel diagnostics are fast, phone/tablet diagnostics are even better. A small price for Fluke/Netscout level network test equipment. Disadvantage: The 300-cable test function does not require a cable to be installed in the switch. To connect WiFi to your phone, you need to turn off the phone's mobile data for a proper connection. Would I buy again, yes. Here are some things Netscout can improve: 1. Turn off your WiFi connection. Use Bluetooth and install the app on the phone/tablet for iOS and Android.2. Enable the option to send a report without a cloud. The cloud is free for the first 120 days and thereafter limited to 10 free days per month. 10 cents per report after.3. Replace AA batteries with rechargeable ones.
