Works great have a few of them very basic. Great to check continuity

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.

Easy to use.

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.

Seems to work well and do it’s job so far. Would rate it higher but hate the way they did the batteries. Only one side has batteries, expected both sides to take batteries but that isn’t my issue, opened the smaller side (which isn’t the side that takes batteries). That side opens easily, the other side however the screws are so deep and small was a challenge to find a screwdriver to reach them. Fortunately my wife had an eye kit with a tiny long screwdriver that would fit the small deep whole. Poor design, can’t rate better as that was very frustrating and I am sure will continue to be frustrating everytime need to change batteries. Be aware doesn’t say online but package when it arrived said “batteries not included”, strangely enough that notice was hiding a pair of batteries.
