Great device I will use all the time, sad it had no instructions
Sturdy and well-built product that I will use all the time. It was easy enough to figure out the basics, but I wish it could go further, maybe with some instructions. It's kind of a good or bad result. It either works or it doesn't, instead of indicating a short or wrong pin configuration. It's just a quick way to check if a wire is functioning but not how well it is doing it. Still, it's a great tool to save time when unsure if a cable is working. I like that it tests HDMI, audio, video, and networking cables.

Great product for testing cables
Works perfectly. Just line up how may leads the cable has and then connect them to see if any of the connections are bad. Works awesome.

cable tester
The MFL 13-Plug Audio Cable Tester has been a game-changer in my audio setup, providing a reliable means to troubleshoot and ensure the integrity of my audio cables. From the perspective of someone with a bit more experience, this cable tester stands out for its simplicity and effectiveness. It's user-friendly, allowing me to quickly identify faulty cables and diagnose issues without hassle. The versatility of this tester is impressive; it accommodates various plug types commonly found in audio equipment. Whether it's XLR, TRS, or RCA, this tester covers a wide range, making it a go-to tool for checking different cables in my collection. The build quality is solid, with durable casing and clear indicators, making it easy to read the test results. It's a compact and portable device, fitting easily into my gear bag, ensuring I have it on hand for gigs or studio sessions. However, while it effectively checks cable continuity, having additional features like signal strength indication or phantom power testing could further enhance its utility, especially for more comprehensive audio diagnostics.

The last cable tester you will probably ever need
One note: the version in the pictures at time of review indicates there is an RJ11 tester built in, which is not the case, the new model now has USB-C to USB-C test capabilities instead. I ended up making a couple RJ45 to USB adapter boards to be able to test all USB cables (works great), and have RJ45 to RJ11 adapters to test RJ11. One could really make adapters to test any other non-included cables were they inclined to do so, as between the RJ45 and HDMI inputs there are many paths that can be used (eight for RJ45 and 19 for HDMI). Just something to keep in mind. Now on to the review... This will test just about any kind of cable found in the home and/or home studio, and it does a wonderful job. The best part for me is that you can detach the two units and test cables in place, not having to pull them from installed positions. This to me is worth the cost premium over the other two units, because I have many (TRS and MIDI) cables in place and wanted to be able to test them without removal should I have an issue, and for that it works great. Luckily I have not had to use it for troubleshooting yet, but have tested some cables before implementing in my setup and it did the job wonderfully.

The detachable feature is a must for installed cabling. Works as advertised. Note that an intermittent short may test fine because it's intermittent :)
