Simple & Accurate
This simple tester lasted me 4 solid years and hundreds of tests on a single 9V battery. I had to replace after a super-5 minute downpour in Chicago soaked it (along with a few other items) while I was up in a boom lift at 50 feet. After it dried out it constantly read "miswire" on all my crimps even though they were good. Didn't hesitate to purchase another one... next time I'll make sure my dry bag is zipped up!

As a advanced DIY'er building a security camera network, this tool has allowed me to check all my Cat 6 runs and fly leads. The removable remote is nice and small and lightweight. I'm on the fence with the LED; I have a short and all I know it's a short on the cable but I don't know what wire is the issue unlike other tools that do show the status of each of the 8 wires. But the result is the same - I have to chase a 200 foot wire for a problem. Not a cheap tool but a good size for your toolbox and simple to use. I always say you get what you pay for and I'm happy with this gadget.
