Useful if You want to know if a cable has a bad connection or is still good!However, it will not tell you the Resistance through the cable. The indication is only in LED lights.Also, another useful situation is when you're looking at a cluster of unlabeled cables and you don't know what cable goes where You put the transmitter part of the gadget on the destination room cable end. And then check each cable at the cluster end for the output signal coming from the transmitter.Durability: It looks like it could handle getting dropped or stepped on. The two parts do slide together, Just don't drop them while there "Slide Together"Batteries: 2 AA, Small Phillips screwdriver needed to install or change batteries.User Friendly: No reading required, at least for myself.

I did not plan on writing a review for this cable tester but the packaging was so much better than budget priced competitors. I had to post pictures. Other cable testers I purchased here at Amazon came in a ziploc bag. To make things worse they are shipped in a padded envelope which offers no protection for the receptacles or protruding connectors. The Sperry cable tester is blister packed so that it can withstand the punishment of being shipped even in an envelop. I did a quick test with the provided cables and everything tested okay. That is when I noticed that the indicator lights are only on the remote unit. More expensive cable testers have indicator lights on both units to determine which end of the cable has a problem. The Sperry TT64202 cannot be used with RJ-45 cables that have current running through them like ones used on phones or security cameras in an office environment. Although the downloadable manual says no batteries are included mine did come with two AAA batteries.

We did some renovations at our house, so I ran 12 runs of cat6 throughout the house and some up to 100'. After crimping on the RJ45s, I used the Sperry testers to check the wiring and it they worked great. I only had 1 bad run, which the Sperry tester picked up on. I had 1 brown wire that turned out to be just a tad short, so the Sperry tester indicated the bad connection on the 7-8 LED. It worked exactly as advertised. I tested it for a couple coax runs and it worked on those, too. Worth the money for sure.

I really like the Sperry brand. This is my second purchase, the first lasted maybe 4 or 5 years and then just died. It does a great job of diagnosing coax, twisted pair and any other cable you want to check. A+

I work in the Telecom/CATV industry. Used this tester one day to trouble shoot a coaxial line. Customer was having issues with pixelation on his TV. Used this tester to test the coax line, it showed it passed. Customer still had pixelation. Ran a new coaxial cable to the cable box, pixelation disappeared. So what lesson did we learn from this? tester passed the coaxial cable, but unfortunately the cable was damaged regardless. Not very accurate tester. Please note i changed fitting on both ends of the cable, my issue was still present after testing the line, hence this tester doesn't really verify the integrity of the cable, just shows pass or fail. Same thing with the cat6 aspect, does not show the actually integrity of the pair or conductor. Regardless, its a good tester to just test basic terminations, not for professional troubleshooting in CATV or Telecom industry.

Does a splendid job of telling that you've wired an Ethernet cable right or wrong. Exactly what it is supposed to do.

This thing works so well. I have tried purchasing other testers and it ended up being lost time and money. This one is very easy to use and works great. This ethernet tester is the "real McCoy". Going forward I will simply order these for my techs.

Works like a charm. Like the robustness of the tester. A great little tool for my networking toolkit. Now i just need to get a carrying case or bag. Definitely recommend this tool.

Uncomplicated and works well. It was easy to identify what cable I needed out of my mess.

Handy to have for sure especially when making your own custom length cables to make everything look clean.
