I have gone through 4 or 5 of these toners personally now, and several coworkers have had a few. The number one problem I run into with then is the LEDs going out, we've had 2 or 3 become useless after that. I've had 1 catch on fire while I was testing a cable, they have a warranty for stuff like that so I was able to get a refund, and that was a one off instance, have not heard of it ever happening before or since. I lost my last one by dropping it down a conduit that went 2 floors down, if I would've found it I wouldn't have been surprised if it still worked, these things can take a beating.
The $300 toners you can buy do the exact same thing this does, don't waste your money on an expensive tool when something like this will do the same function for a fraction of the cost.

The media could not be loaded. Wow, this network cable tester and tracker exceeded my expectations, and here is why.

This product includes a carry pouch, a user manual, and some network cables. It consists of a wire tracker receiver that requires a 9-volt battery not included and a wire tracker that requires a 9-volt battery.

It works by connecting a cable to the tracker and using the receiver at the cable opposite end to confirm the line.

I needed to track a cable from my outside work area that runs underground to my basement. So I connected the tracker and headed to my basement.

I recently moved to this home with dozens of preinstalled network cables and used the receiver to check them all. I like how simple it was to use, and it eventually located the line. I was able to identify it and label it for further use.

Overall, this is a fantastic tool that works as described. I didn't expect it to be this easy to locate a cable among many. What a time saver! It is well worth the price and I highly recommend it. Therefore I rate this product five out of five stars.

This worked surprisingly well. The cable tester shows any crossed pairs or broken pairs, and the toner seems to work flawlessly. The toner is a "little" quiet but it worked for my purposes with no issues.

The carry pouch is good.

It does need two 9v batteries. Order them too as it doesn't come with them.

Good enough for my minor wire ID and the right price. I think it may do other tasks that I need but the instructions are translated nonsense. If you know what you want to do, this tester is fine.

Takes 2 9 volt batteries which sucks because who has those anymore? I know the ad says they're NOT included. But it also says they ARE included. Packaging also says so. NBD but annoying.

Good purchase for $24 dollars. Bought a new house and had to trace some cable from already installed ethernet jacks in the rooms. Plugged the tester in the jack, went into the attic to start probing for the right cable, got a good loud tone on the first cable I checked. Tried another jack, for the phone this time, took a little searching but got a good tone on the right one, not as loud as the first, but positive ID. Definitely worth it. Feels cheap, but works well.

Shame on Amazon though, shipping label was just slapped on the product box and the ends weren't even taped shut. The delivery driver could have opened it up, used it and placed back in the box, and I never would have known. No star removed because it wasn't the manufacturers fault... good product.
