Versatile, Easy To Use and Operate
Before you start using this tester, remember to connect the battery cable first :). It came disconnected for safety as well as to keep the battery from draining. The Probe battery is already connected, and there is no accessible battery compartment, so I just went ahead and charged it up. As stated on the product page, the Emitter has a 4000mAh rechargeable battery inside, and the Probe has a 2000 mAh that should last up to 12 hours depending on usage. To be honest, I have yet to open up the User Guide to read. I just watched the little demo video on the product page and then tried it out. Functionality-wise, this tester comes with all the things I needed to test my home network, as well as cables, not to mention the Digital Multimeters that I could use to test AC/DC Voltages, Currents, Resistance, and Diodes, amongst other things. The Auto function works really well, going from a small battery to my 120V power outlet. Anything over 36V, it will light up a RED warning of High Voltage present. But that is not all, the Probe can be used as non-contact AC Voltage detection as well, it’s super convenient to have it.As far as cable testing, it’s quite accurate. I had an Ethernet cable that looked normal, but I just couldn’t figure out why it wouldn’t connect. So I plugged it into the tester and the Probe, ran the cable test function, and it turns out that the Orange cable was damaged under the shield, now I know :). I also used it to locate cables between my guest bedrooms and the bundle in my attic using the Cable Search function. The Cable Tracer also works well; it’s used to trace the path of IP packets between two points. For example, I tested it using my local IP address and the Amazon website, and it took about 20 Hops with the time in ms. I have also tried out most other functions as well, too long to write them up, but they all worked as expected. One thing I have yet to try is the Optical tester, since I don’t have any optical cables to test with, but I will try it out once I have my hands on them. Other than that, I really like the versatile Tester, love the Multimeters and Probe functions as well, it seems well-made, rugged, but not too heavy or clunky. It comes with a very nice zipper carrying bag as well as wrist straps. I do think this is a great value to have, almost an all-in-one cable tester. Before I forget, remember to set the IP address for this Tester to Dynamic if you need to run some Network tests, since it’s pre-set as Static. One last thing, the Built-in LED lights on the Tester and Probe are a big plus for me also.

Other than lack of charging information, I don’t have any complaints so far.
Yeah, lack of charging information… Unless I have missed it. And if I did, then it should probably be easier to find. The only charging information that I DID find, is that the main device (the emitter) has a battery with a capacity of 4000mAh with a working time of about 6 hours, and that the other device (the receiver) has a battery with a capacity of 2000mAh with a working time of about 12 hours. But then they give you a cable that has a USB-A connection on one end and TWO USB-C connections on the other end, which is very cool. With no charging information though, customers have no way to know what kind of charging brick they’ll need. I wouldn’t expect something like this to come with a charging brick, so that’s no problem in my opinion, but not everyone uses charging bricks or charging stations that show the volts, amps, and/or wattage that devices charge at like I do. And so, to those who don’t, it looks like each of the two main devices can charge at a maximum rate of 10 watts. So to charge them as quickly as they can be charged using the double USB-C cable that’s included, I suppose you’d need a charging device that has an output of at least 20 watts.Well, like I had said, I don’t really have any complaints other than that. However, to be honest I wouldn’t put too much stock in my opinion. Especially if you are someone who professionally uses something like this. Because this is the first time that I have used devices like these, so I don’t have any other basis for comparison.One more thing. Even though I like very much that it comes with a case for everything, the quality of the case isn’t that great… Because I spent a good thirty minutes or so trying to repair all of the loose threads on it. It’s not a super big deal though, as I WAS able to repair it. And that might not bother other people like it bothers me either. So I didn’t reduce my rating any for that. I only took a star off for lack of charging information.
