CERRXIAN RJ45 Coupler Ethernet Network Surge Protector Extension Adapter(2-Pack)

Been using 2 years without a problem, but how would you know if it did anything? I got these after an ethernet port on my router got fried where I had it connected to another building. I used a different port and installed one of these on each end of the wire with a 1 ft patch cord.

So far so good, of course only a surge will tell in the fututre. Well made and fit perfectly . We had a lightning strike come in through the cable took out tv modem and royter and cable box, had surge protected wall oytlets but not the cable

Work fine but 100Mbps Not for 1Gpbs NICs

We had a lightning strike that took out all sorts of stuff, mostly internet stuff including stuff that was on surge/UPS protection. I now have an earth grounded surge protector on the twisted pair that comes in from AT&T. We assume that's how it got in and spread. These are in-line and don't require an earth ground so I put one on my generator (lost the logic board on this) and one on the line between my gateway and my switch.

Good job so far

Product very good, fits my ethernet cables perfect

Don't waste your money! Total Fail in both directions! Storm in the area, no lightning strikes on property, the closest one was up the road (maybe 1/3rd to 1/2 mile) and we heard a loud pop in the house like someone had fired a .22 rifle inside. Discovered both ends of the 75 foot fully shielded Cat7 underground class buried cable between the house and a seperated apartment which was protected at each end with one of these had burn marks where they plugged into these. Inside the house we lost a $200+ router and a $100+ gaming spliter in the apartment. Checked them and they still allow signal through even now and they should not after a surge! Which means they allowed the surge to pass straight through never tripping themselves ~ the whole point of this design of this kind of SACRIFICIAL surge protector is that they are SUPPOSED to pop themselves to protect the other equipment but they didn't! Total Failure!

Very good quality and very strong
