It's a simple tool but it got the job done and was easy to use. I like the tool very much. It's super convenient and inexpensive. There were some CAT5e cables around the house but the previous owner didn't really use them so I had to find some leads on the main panel. That made the work reliable. I just wish they had all the wires going into the jumper. Thanks to this, the tone that went down one line was present in all! Very strange setup so I had to undo the whole thing. This can be useful for phones, but not for network cables.
