NEWCARE HDMI Surge Protector, Mini Portable HDMI 1.4 Protector for ESD and Surge Protection, Support HDCP 4K 30Hz - 1 Pack

It looks great technically, hopefully it works when a surge happens....

Trabajan bien.

We had several instances of lightening coming through our HDMI ports. This has helped a lot to stop that

My four-week old computer just lost its display port video because of a nearby lightning strike. Where I live, you can expect a t-storm almost every summer afternoon. Because I still have a working HDMI port, I found a cable and hooked it to my monitor. My computer lives! ...for now. I'm worried about another strike taking out my only remaining video port. So I start searching around for solutions and I come across this. It's cheap enough, so I buy it and plug it into my computer before the HDMI cable to the monitor. Cross your fingers..... About a week later, my screen goes blank and I hear thunder. It stays blank. With a bit of trepidation, I crawl under the desk, remove this device and plug the cable back into the computer. My screen comes back! Great, but this gizmo is dead. It's not smoking or anything, but video signals aren't passing through it. So..... I have to buy another one? After a week? Maybe I should buy a dozen...... I decide to ponder the situation a bit and start looking for another solution. A couple of days later, I see this once-useful thing sitting on my desk and decide to toss it out. Before I toss it, I put it back on the cable....and I still have video! Did this gizmo need to cool off or something? Does it reset itself? I'm not sure, but for now, it's going to stay on that cable. In the meantime, I'm going to put a big, galvanized piece of sheet metal against the wall behind my desk - it's in the garage doing nothing, anyway....

Only a surge will tell, but so far so good, well made and fit perfectly. Had a lightning strike come in through tv cable took out tv, modem, cable bix, router. I had surge protected wall outlets but not the coax cable.

Hope it works.. haven't had any outages as of yet but they were easy to install.

Product work as described

THEY DIDN'T WORK! I put one of these surge protectors on each end of my HDMI cable. I have only one cable, and it connects my tv to my dvd player. Recently we had a lightning storm pass through our area and a surge entered my home. I have surge protectors all through my home and they all did what they were supposed to do. Except for the HDMI protectors! My 75” TV’s HDMI input board was completely burned out!! Fortunately I was able to have the repair made under warranty. The entire reason why I bought these foolish surge protectors was to Protect My TV!!!
