Excellent
The fact it divides in two is so helpful!

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

Increíble herramienta!
Super herramienta, muy útil a la hora de probar el cableado, el generador de tono facilita mucho el line check, el poder separar el tester es de lo mejor.

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.

Muy bueno !
Muy versátil y cómodo a la hora de revisar cables instalados ya q no requiere q los dos extremos del cable se encuentren juntos para testear.El único punto a mejorar es el compartimiento plástico de la batería 9V, ya q en mi opinión lo ideal seria q llevara pilas de litio recargable para evitar que se sulfaten por olvido
