Perfect for cable tests and Fiber Troubleshooting
The device has a Variable Frequency Laser (1Hz, 2Hz, and Static) that is good for shooting light to find faults in fiber or locate where a connection is on a patch panel.Also has an Optical Meter to test how strong the light coming in is from another Switch/Router/Media Converter. I keep this in my car and it’s saved my but a few times when I ran into fiber issues and was able to do some quick troubleshooting. Just gotta remind myself that -16.00 db is the “normal” threshold for a good fiber connection.The Ethernet parts work well too.Positives:Flashing Port = checking for connectivity. Provides speed, duplex, etc. It’s good to know if I am even getting a good connection to start with.QC = If I am actually getting a copper contact on the termination. Good for when I make my own cables.Cont = This requires you plugging it into the port on the Toner on the far end so you can see what the cable is doing. Good for finding breaks and splits.Length feature is pretty accurate. Sometimes it’ll show a pair that’s not broken or anything as being way off. So you kinda gotta use your own judgement in some of these cases, but that’s what we network engineers are paid for, right?Cons:Often find myself needing to use the port on the Toner for the most accurate results for the CONT and I have had some issues with using the actual toner correctly. But this likely was user error since I rarely ever tone anything out.All in all, it’s definitely worth when working on a large network where you have a mix of copper and fiber. Especially when the name-brand competition has their products in the THOUSANDS of dollars price-range. So this definitely does the trick for me.10/10 recommend.

Great little multipurpose network tester. Accurate enough for most IT work.
I’ll be honest, I wasn’t expecting a whole lot from this set, since some of the things advertised generally require much more expensive and far more accurate tools. However, I was pleasantly surprised how good it actually is. I really like the dual mode wire tracer (Digital and Analog tone out) and the cable length measurement is actually quite accurate. I tested the fiber functionality and it also seems to be good. I purposely tested a known good fiber and then damaged it by hitting it with a hammer over the edge of my bench and it detected the change in light. It seems like it would be fairly durable and it has decent battery life and charged fairly fast. Is it a Fluke killer? No. But it’s accurate enough for 99% of my day to day IT work.

Feature-packed tester with a learning curve
This device does more than a standard cable tester, with functions like IP scanning, PoE testing, port flashing, and network rate checks. For IT or network techs, it provides a lot of useful data in one unit. The TDR function is helpful for identifying cable faults and distances. The interface isn’t the most intuitive, so expect to spend time with the manual before you can use all features effectively. Build quality feels solid, and it’s reliable once you know your way around it.

Nice kit! Well worth the cost
I do a lot of network support, but I don’t make my whole living from it. So I can’t afford $5000-$10000 tools from the big manufacturers.But I still need to check fibers and Cat 5/6 cables and this unit does both very well.In particular, having the optical power meter means I can plug in a fiber and quickly find out if light is getting through from the other end. I can also get a feel for how strong the signal is. I’m sure it is not calibrated precisely, but it tells me if the circuit is in good shape or if it needs work.For ethernet cables, it does simple testing to ensure all pairs are connected right—but that is common. This one also allows you to estimate cable length (TDR functionality).Better yet, you can use it to check if a cable is live, tell what speed got negotiated and even find out of POE (power over ethernet) is active. This is something I do all the time—a basic “is this live?” test. But before I got this, I had to bring along a computer with an Ethernet adapter dongle.The screen is color and is very clear. My only minor frustration is that it looks like it should be a touchscreen, but it’s not. You have to navigate using buttons. They never said it was a touchscreen, so it is fine.FYI, the most common kind of fiber jack/plug is called LC. This kit has a different jack on it called SC, so be sure to pick up a patch cable and/or adapter that converts from SC to LC. These are not expensive.

Compact size and include all tests most need at a great price
This is a tester that combines all my cable testing needs in one complete and compact package. Rechargeable is also a great help. Charges last months. Nice. I no longer have to have 4 or more separate test devices. I particularly find the cable length function useful. I can now tell how much wire is left in a box or on a roll. That in in it self save a lot of time. Very good quality.

[UPDATE – 18Nov2025)Another use for this kit just came around. I was watching videos on guys repairing LED Christmas lights.Some use an NCV (Non-Contact Voltage) detector. I realized that this kit has a dual detector, for both Network signals AND voltage. In fact, there’s an NCV button on it.I took it to a string of LEDs where one side is out and sure enough, this was able to detect where the voltage stopped. That was the bad LED!Seriously, I really like this kit and do highly recommend it.After having this now for a few months and using it with every cable I ran (and i ran, so far, over 16 CAT6 Solid Copper) I can say that this product is just excellent!Sometimes I had unexpected issues with the crimping tool, where, it seemed ok, but when on the network, it would totally fail or be “glitchy.”This meter was able to detect the issue! Not only that, where the little cheap tester would say that the cable had good continuity, this meter could detect that it did not.In fact, I had a few times where the crimper caused a very light “short” in the wires (or even crossed the wires in the connector).Not only was this meter able to find it, but it was even able to confirm which end of the cable had the issue.Another feature that turns out to be seriously necessary is the Length test.I had a few cables that the meter reported as having a short. But where!?Well, what I did was to test length from each end, one at a time. The numbers reported revealed where the short was!Example, from one end, let’s say, 6 wires tested the correct length, while 2 were not right, or tested as crossed or open.But test at the other end, now we had numbers that revealed which side the issue was on.In one case, I had a run that was about 40′. I hadn’t noticed that the cable got a twist (kink) in it, but when the cable failed, the tester, using length from each end, revealed approximately where it was.I pulled the cable and sure enough, the kink was visible! I was able to cut the wire there, put a new connector on and problem solved.I also got to use the scanner function as my markers on a few cables fell off. I was easily able to confirm which wire at the wall was the wire going into the router. It just works!Seriously, if you are going to do a big job, like I did here with a full-house rewiring job, this device is a must-have!________________ original review follows ________________________I’ve had this for a few days now and I’ve tested cables in our setup.I’m very impressed how well this works and how many features it has at this price point.I have to do a full wiring of our house, greenhouse and garage, so this will be a necessity to test all connectors and wires.I do recommend this tester.
