Review on Wsdcam 7 Inch Retina Display IP Camera Tester for CCTV, CVBS Analog Systems with POE/IP Discovery, WIFI, 8G TF Card, 4K H.265, HDMI Input and Output, RJ45 TDR, Firmware Update - Upgraded 8600-Plus by Travis Chavis

First of all I have to say that this is not the most portable device as it is much larger and heavier than I expected. I don't even own the top model, but this thing is feature-packed. It also updates automatically as long as you are connected to WiFi. It opens, loads and scrolls through apps quickly. There's even a Chrome browser. Also, the battery lasts forever even when using Poe cameras. The device seems sturdy enough to survive a fall. Comes with a nice soft pouch for extra protection and for carrying extra test leads etc which are included. Despite being a heavy beast, it can be held with one hand thanks to the straps and good grip area. While some have complained about the included cable finder, I found it worked quite well.
