    Definitely a handy tool to have in your garage.
    Helps a lot on diagnostic procedures and also testing of equipment.
    This product will eventually be displayed in my videos on my Channel called AlexTheGrumpyOne.
    Feel free to find many products and reviews on there.
    Always happy to give a good honest review.

    Nice bit of kit easy to read and use comes in a nice case with extension and two different connection types crocodile clip to battery and cigarette lighter connector the only criticism is it comes with one removable tip dunno how easy it is to find a spare

    This has quickly become my first choice for car electrical diagnosis work. Much faster than using a multi meter, can check for power and earth without adjustment, just probe the wire and the screen tells you.
    The ac part works better than expected too, without any settings to adjust I thought it would be useless but far from it, it was easy to identify can hi and can low lines on the screen. The power testing part works great too, no more messing around with wires or removing parts to bench test them. Worth every penny, paid for itself in no time.

    A couple of down sides. Buid quality is not quite to the same standard as the branded version and the lack of a banana probe end means that you can’t back probe with it.
    Otherwise a great piece of kit and a great time saver.

    This was a surprise as it had more features than some big name brands and cost a LOT less. Quality was good and evrything worked out of the box. Cables and wiring are substantial. In use everyday in my Mobile Diagnostic busines.
    Well pleased.

    Golden Review Award: 2 From Our UsersJust used this to help me determine where the fault was on my van electric window that’d locked in the open position. Could’ve been the switch or the motor/regulator. Both of these items would cost around 100 plus diagnosis. Managed to determine that the switch was OK and it was the motor at fault. Ordinarily the advice would be to change the motor but disassembly showed it to be a 5 minute job to put that right. Everything reinstalled at it’s working fine. About an hour’s work and saved 100+. There’s more expensive versions of this tool on the market but this one does everything the others do at a bargain price.
