Like you I probably wanted the cheapest ethernet tester as I don't test ethernet ports/cables very often. I found this ad and thought it looked perfect! And that's how it would have been if DOA hadn't existed. I cracked it open to see what was wrong and the 9v adapter had bad solder which broke. I soldered it again and now it works! I added a dab of hot glue to relieve any tension in the future. A simple solution. I've just tested it with a cable and it works fine, although I'm a little surprised at how the LEDs perform. On most cable testers, the lights on the local box (large) _always_ light whether a cable is connected or not, so you can look at the local box to see which cable is being tested and at the remote box to see which cable is being tested to see if it is connected. is continuous. With this tester, the local lights only come on when the wire is continuous, which is a little frustrating. In general, this device will satisfy my needs, but if I didn't know how to solder, I would do a lot more. upset, hence the bad rating.
