    Multi-Function F-Type, RJ-12, and RJ-45 Cable Tester

    Cable testing cannot get any easier than with the Monoprice EZchecker 008 Cable Tester.

    This tester is a quick and easy continuity checker for RJ45 (STP and UTP), RJ11/12, and F-type and BNC Coax cables. It tests each conductor on RJ cables and instantly provides a pass or fail result, with an indication of which conductor is faulty in the event of a failure.

    The tester consists of two pieces: the Master unit and the Remote Terminator, which can be detached from the Master unit by sliding it off to the right. There is no on/off switch or test button, simply connect the wires and get your result. Nothing could be easier!

    WARNING!!! Do not test live circuits as it could cause damage to the tester unit or personal injury.

    Note: This product has a universal card packaging that is used for PIDs 8129, 8130, and 8131, with the individual model marked on the back. The front of the packaging includes functionality tags for all three testers combined. Therefore, the packaging erroneously indicates that this tester is capable of HDMI cable testing, which it is not designed to do. For HDMI cable testing, please usePID 8131.

    Also note that the back of the card indicates that this unit can test USB cables. While it is electrically capable of doing so, the necessary adapters are not included with the tester.

    Tests Continuity Alright
    If you are going to primarily use this for network cables, I would recommend product ID 8130 instead.

    PROS: Quick and easy to use.

    CONS: Does not test for short or crossed lines. Therefore, if the cable shows that it passes, it may still not be ok to use.

    Worked Great!!!!!
    My Son just bought 35 years old house. He had hard time to understand why his F-Type connection in every room were not working. So Him and I used this Multi-Function Tester and found all right connections (in the Attic). We also found several unwanted F-Type cables in the attic. This Tester made our lives very easy. Yes, it took us only 45 minutes. To us it is the Wonder tool.

    Looks good...
    Great looking unit and priced well...wish I have bought a different one since it is not reliable

    PROS: Nice, neat compact unit easy to use.

    CONS: Not always accurate. I have had it test cables and outlet connections as good but they must have been weak. Tested with another unit, showed bad. Replaced connectors and they worked fine. Too bad...otherwise I like it.

    nice and easy to use, and a very good price.

    PROS: very simple and easy to use. a all in one tool.

    The LEDs are brighter than they need to be, and can be almost painful to look at. Opening the battery compartment and closing it with a battery inside are both far more difficult than they should be, though possible. That said, it seems to work as advertised, though I've only used the coaxial and RJ-45 testing so far.

    This device is useful for novices.

    PROS: Easy to use.

    CONS: Can't tell if you have a crossover cable.

    Nothing special
    It tests continuity, but it doesn't tell you if there are swapped pairs. It a very rudimentary cable tester.

    This tester certainly tests continuity on all pairs, but does not detect reversals on a pair. it makes this tester totally useless. Definitely wouldn't recommend it

    broke in about two months

    PROS: easy to use

    CONS: already broke

    Response from Monoprice

    Thank you for your review and my apologies for the issues you have experienced with PID 8129. Unfortunately, it sounds like you may have received a defective product.
    Now if you'd like, I can help setup an RMA for a replacement. If you would like me to proceed with the RMA, all I would need is the order # this cable tester is under. Sorry again for the trouble and thanks in advance!

    Quick and simple
    The lights on this tool was quickly able to indicate where in the connection from the switch to the computer I was having issues. Specifically it has helped identify a loose punch-down on a drop and a couple of bad Cat-5E from drops to computers.

    This is a simple tool, as the price indicates. Advanced features for detailed troubleshooting and identifying issues should look at other tools. Those tools should be used for Full Time Network Admins and Engineers.

    PROS: Quick Simple

    CONS: ...eh, wish it came with some short RJ-45's for checking Patch to Drop.
