These connectors work very well. Useded them as a pass through in a project that I am building. The connectors are a good plus even though I didn’t need them at this point.

Installed Funlux 8 camera sPOE system. Needed to extended 6 sPOE cables to reach the NVR box. All couplers worked great. I also used all 12 of the RJ45 module plugs that came with the couplers. After crimping each plug to Cat5e cables, the plug attached to the Dinger couplers without any issues. I'm wondering if reviewers who said the RJ45 module plugs didn't fit into the coupler realize you must crimp the plugs to an ethernet cable first before inserting it into the coupler. I will definitely…

Very nice, solid couplers. I don't have to worry about them breaking if they get stepped on (not that I would install them where that could happen!). Running GigE speeds through these without any problems.

I used these to extend my Ethernet cables for my POE surveillance cameras. Have worked great, I’m getting excellent video from my 1080p cameras. Would buy again.

I used to make my cables, so I have not needed these before. Had some pre-made cables around, and this was the quick and easy solution!

I increased my rating from 2 to 4 after receipt of an email from Dinger the day after this posting. They offered a quick replacement and an apology for the problem. Given the ratings from others, I will assume I received a bad run. In my book a quick response to a problem compensates for a lot.I cannot get any of three brands of RJ-45 connectors to insert into this product. Including the package of RJ-45 connectors that came with it. It will accept with my older pre-made cat 5 cables. I managed

When all you need is to connect multiple cables together to make a longer cord, this works beautifully. And they are quite durable. I have had others thru the years no where near as nice as these. I don't foresee any issues with these high quality connectors.

I was VERY surprised with the exceptional build quality of these couplers, fabricated in durable, but not overly weighty or sized metal casings, as well as with exactly fitting female sockets at both ends. Best of all, I noted no decrease in download speed, compared to that of the source, even with two couplers in the extended CAT 6 line! All the couplers in the order worked similarly well, and identical in finish details.BOTTOM LINE : Excellent value, superb performance!

I bought these rj45 connectors for extending cat5 cables from my router to different rooms and they work really good strong signal.

UPDATE 6/282017Seller reached out to me via email to rectify any and all issues. Considering the cost I don't see a need for a lot of time being spent on dealing with the issue. Things happen and that is a fact of manufacturing.included RJ45 connectors will not fit in the couplers. Unable to use the product. Looks well made but if the connecter won't fit the coupler is useless.I tried several RJ45ez connectors and they too will not fit. Actually insertion is impossible. These looked like good…

RETURNED ITEM IN MULTIPLE ITEM PACKAGE, but getting "not returned" message>>>?Dingsun RJ45 Coupler, 4 Pack Cat5 Coupler with 8pcs RJ45 Connector Ethernet Cable Coupler for Cat5 Cat5e Cat6 Cat6e Cat7, Support 100BASE-TX (Black-4 Pack)Sold by: Dinger-US

These work exactly as they should. I needed to run a cable thru a tight area. I didn't want to cut a big hole for the ethernet plug end. So, instead, I stuck one of these on one side of the wall and only had to cut a small hole for the wire. Perfect!

Just using these for indoors only, so I don't know how well these would work for outdoor usage.Nice and sturdy, compared to older RJ45 bridge couplers these are really nice.

These feel well built, as if cast in solid plastic, and seem to do the job well for what I needed. I needed to extend a run of cable to hard wire my TV, and now it works great without any buffering whatsoever. I got a great price for eight of them, so I have seven spares now as these come in handy once in a while.For those of you lucky enough to be running fine hardware at 10 Gbps over Cat 8 wire, possibly in a scientific institution or data center.I'm afraid I can't help you on how well these…

This is a great deal on a great product! A Flawless way to extend your eithernet cables! If I ever need anymore this will be my absolute choice!
