I lost over $80 of toner so I was hoping to tint a cat 5 at a time. This stuff is so good that I can find the audio in over 300 feet of cabling at the other end of the commercial building Cat 5 signal and at the same time over the coax because both the RJ11 alligator clips (connected to the coax) and the ethernet Port "testers" can send a signal at the same time, saving me valuable time trying to figure out where things are going. . Also, the thing doesn't turn itself off automatically. I worked for hours at work, forgot my toner was there, came back and was still banging loud. Great product, definitely cheap and you need to be more careful with it, especially with the alligator clips, the solder came loose from the RJ11 chord, I "resoldered" it with a lighter in my pocket. So as I said great product for the money as far as wire tinting goes, have never used the 5 pin test but probably is something too.
