## Before you buy

- The listing claims 10Gbps transmission and up to 100 metres, but these are manufacturer claims and depend on the connected cables and network equipment. The stated distance should not be read as a guarantee of a particular speed over that full length. The package is listed as one coupler.

## A good fit for

- People extending an existing Ethernet cable run with two compatible RJ45 cables.
- Home or office users seeking a compact female-to-female joiner for Cat 5e to Cat 8 cabling.

## Less suited to

- Buyers who need a complete Ethernet cable rather than a cable joiner.
- Installations that require a verified throughput guarantee or confirmed performance over a particular cable length.

## Customer feedback

Customer feedback describes the coupler as easy to use and effective for joining short Ethernet cables, with reported satisfaction around connection security, speed and build quality. These experiences fit its intended role as a passive cable joiner, though they do not establish a guaranteed data rate for every cable run. The aggregate rating is strongly positive overall, but ratings alone do not identify performance under specific network conditions.
- Positive themes: Customers report secure connections and say it works well for joining two Ethernet cables.
- Positive themes: Feedback highlights ease of use and a solid-feeling build.

## Frequently asked questions
