Review on Optical Ethernet Network Analyzer for Portable Disorder Testing, Measurement & Inspection by Osoulo Sharp

I upgraded my home network. This tool didn't work very well when I got it, but it got the job done the two times I used it. And after a week it stopped working at all. I have used brand new batteries and the device has not been dropped or abused. It's just cheap junk. Luckily, Revain has a great returns policy, the only saving grace.
