This is an old video I released on Elliot’s Extras back in September 2023. It didn’t get a write up on the blog at the time, so just doing that now. In this video, which was the first ever video for Elliot’s Extras, my second channel, I organise some of my diodes from AliExpress. This is a really long and really boring video, a perfect fit for the first Elliot’s Extras video. :)

Unboxing #12: Unboxing and Demo of OULLX NSS-681HDMI-RJ45 Cable Tester from AliExpress | In The Lab

This post is part of my video blog and you can find more information about this video over here.

In this video I unbox the OULLX NSS-681HDMI-RJ45 Cable Tester from AliExpress and compare it with the Ampcom Automatic Network Cable Tester also from AliExpress.

OULLX NSS-681HDMI-RJ45 Cable TesterThis is an image of the product.notes
Ampcom Automatic Network Cable TesterThis is an image of the product.notes

Note that the Ampcom is advertised as the ANENG M469D on AliExpress, but that’s not actually what you get. The Ampcom model that you do get seems to work well enough, but I would recommend the OULLX NSS-681HDMI-RJ45 because it’s cheaper and can do HDMI in addition to Ethernet.
