A few days of use, seems to operate ok. Recent alarm may/not be associated with power transmission; investigating that! Real world thought to your engineers please consider an alternate to plastic.

Great product good price and fast delivery it was easy to find on the website ordered and was here in a few days

Used 5 of these RJ45 online Couplers super-glued to extend the 5 ports on my router. Used the 5 pack multi-colored cat6 slim cables for the 5 ports to my router. Looks great, no messy cable mess. Made it easy to plug in new devices into my router.

Not much to say, purchase was real easy, product was just what I wanted, all went as well as could be wanted.

Even works delivering power over the wires (I used Open-Mesh wifi nodes) but "real" PoE probably works too.

Trolls seem to be everywhere writing bad reviews on products just to be contrary.

This coupler is well made. I bought 6 and tested them all on a POE camera. They work fine. They are solid and well made. Don't believe the bad reviews. This is a good product, well made and fairly priced.

PROS: Solid construction well made

CONS: None

After seeing the reviews on these I decided to test all before trying to use. I purchased 10 of these just to have handy in the bag of tricks.

Test 1, RJ45 Mapper, tests PIN to PIN with DC. All tested OK
Test 2, Sunset T-10 DS1 test set to a loop back. (1.544 Mbt) This tests pins 1-2 4-5. of these 6 tested OK, 4 were intermittent. Sprayed with Caig Deoxit, and all seemed to work.
Test 3, 100 gbt ethernet connection to Laptop. (Tests pins 1-2 3-6) of these 9 tested OK, I refused to connect after several trys. Did a lot of wiggling but it never worked.

The one that refused to work at 100 Gbt, worked OK back on the T1 Test set, so just threw it in the test equipment bag as a test coupler. When you get these, test them all before you try it in the field. Some kind of spay cleaner may help those that don't work at first..

PROS: Most will work

CONS: Test before use and figure a 10% failure rate at higher speeds

These adapters are very flaky. Every one of them has intermittent contacts. They pass a continuity test, but I cannot transfer data reliably.

I bought two 30 feet Cat5e cable and a Cat5e coupler because Mono did not have a 60ft cable.

The couple arrived defective but the cables were fine.

PROS: Small and low profile

CONS: Did not work

After reading several reviews from other people that bought these inline couplers, I bought 10 of these even though I needed 9...

Good thing I did too, one of them didn't work completely (tested with a network tester and one of the connections was severed).

Of the other 9 that did work, one was extremely flaky, and I suspect that it is a matter of time when that one fails and I will need to buy a replacement for it.



But when these are working, they do the job just fine.

PROS: They work when they work

CONS: 1 in 10 fail
