HDMI 1.4 4K UHD Surge Protector Kit with Jumper Cable and Ground Wire

Lasted about 6 months, then the TV would get intermittant signal loss on the HDMI. It finally went completely. I am an industrial electronics tech certified in board level repair. It could have been a bad device or had a mfg defect. I did not have any surges or lightning strikes. I do have a 4K TV, but it had been working fine so I doubt the 4K had any effect on the surge protector. To be fair, I have not seen the specifications on this device. However, there was no indication in the documentation that came with (minimal) it that there were any restrictions or HDMI limitations on resolution.

Ground wire was to be connected to the unit with a tiny machine screw that wouldn't fit into the unit. Had to drill out the hole then the screw would go in. Should have supplied a fine sheet metal screw. Then the grounded outlet end had to be redone since my outlet ground screw is a size 8 sae and the supplied lug is 1mm. However, if this surge protector works for my HDMI plugs into my new 4K TV, it will have been worth the extra work installing.

You spend alot of money on your tv or whatever, so protect it from surge electrical spikes that may come through your Cable box, or Satellite system, or even your OTA Outdoor Antenna. It's peace of mind.
