Review on 🔌 Efficient 2-in-1 HDMI Cable and Network Cable Tester by Optimal Shop: Test RJ45 Cat5 Cat6 HDMI Wires by Sean Garrison

Great value for money. Yes it took two tries to get one working but the second unit we got worked. The block is very light and looks cheap, but there aren't that many innards inside. There are 2 buttons: a side slider to toggle between RJ45 and HDMI modes and a front panel button called 'Func' - obviously a function. Press and hold the button for 3 seconds to turn it on; 3 more seconds to change the scan speed and 3 more seconds to put the device in pause mode where you can go through the contacts one by one. If English is your second language, you can try to read the guide with gems like "Smart Tester opens FUNC button" for several test speed selector switch, which is the button for backlight. Light tester boots FUNC button 3 seconds, standard high speed test, easy to FUNC conversion into 1 test speed, gently press and hold for 3 seconds to enter or exit the point, manually move the test mode, press the FUNC button, to light one bright; keep repeating." Yes. Literally.
