Review on 🔌 OREI EX-500IR: High-Performance HDMI Extender over Cat5e/6 Ethernet LAN Cable - Up to 500 Feet - Advanced Features: IR, HDMI Loop-out, RS-232, PoC, HDMI Balun by John Hall

I make a lot of videos and slideshows for company parties. I have listed 4 other 3rd party devices up to 392ft but there is a slight video lag when moving the mouse. It didn't really matter since most customers mainly want videos and slideshows. At a company event last week, the video we showed had a lag in audio. I've never experienced this problem and had to use a video switcher to slow down the audio by 200ms. I decided it was time to find a solution if I'm doing a mixer-free event. I installed this on a website and spent several hours testing it. This device works great with the 50ft, 100ft, and 200ft cables I've tried. Moving the mouse pointer on my laptop and the cursor on the screen moved exactly in time. No delay. I just ordered a second one for an upcoming event. Will likely order 2 more to replace the one I currently have. Good product! As a side note, I had a 100ft cable from Monoprice that didn't work on my other devices. Luckily, Monoprice has a lifetime warranty on the cables. Replacement is on the way. My other Monoprice cables work fine, as do two 200ft direct attach cables.
