    I liked it, I bought it and used it on two cars. I think it is quite fair, simple, and understandable. It measures battery, starting voltage, and alternator. Basically, everything you need. I hope it lasts over time.

    Excellent tool to check the condition of the battery, I had a battery that showed the correct volts, but with this tester it really showed that it was useless, low amps and high resistance.

    You will encounter some difficulties until you get used to the data entry required each time. After that, it will seem easy to you.
    A basic element you will need to provide is the battery's Amps.

    Good tool. It shows voltage and starting amps and tells you if the battery is good or not. I used to have a simple voltmeter always connected, now I read in the comments that it diagnoses the starter and alternator but I couldn't find that. If someone knows, let them say how. Otherwise, even with a simple 3-euro voltmeter you can do the job just fine. Thanks to the person who provided the manual in English.

  • It's just fine, very VFM, does its job as it should.
    It's Chinese of course but it's okay. For amateur use, which is what I want it for, since from time to time something always happens with my relatives' cars or even my own, it's just fine.

    Very useful to see not only the volts and the starting amps of the battery that indicate the "health" of the battery, how much life it has left, that is. The battery must be charged and it should be done a few hours later for the measurement values to be accurate. The crocodile clips (clamps) have side teeth for a good fit on the terminals, it gives an error if the connection is not tight. For an amateur battery diagnostic tool at €10, it is very good.

    Although it has relatively small crocodile clips and does not easily connect to the battery terminals, it provides accurate measurements and some additional information about the battery's condition, some of which may be difficult to understand for an average user... It is powered by the battery that is connected for measurement, and if the battery is dead, then the device will not turn on either..!

    I believe it is perfect for someone who wants to control their batteries on their own. The only downside for me, as I am not familiar with all battery technologies, is that it has many battery options/properties that I am not familiar with. It does its job just fine.

    Very good tool, it has "solved" my hands!
    I've been looking for it for a long time. Before you even press the starter, you know what to expect.
    No matter how many times you measure, it gives the same result, which shows that it works correctly.
    The device showed a faulty battery since the starter was turning difficultly, and ultimately with this tool, it was revealed that the starter cables were not making good contact, as it showed a good battery, and thus I saved the unnecessary battery replacement.

    Measurements should be taken 2 hours after discharge or charging. Otherwise, the indications are incorrect. Otherwise, very useful, it shows the level of charge, voltage, and battery health.

    Excellent device but also the job it does. Everything it says is true. Reliable measurements of both the battery and the car's power, but above all in the measurements of the starting CCA amperes that the battery provides even during the moment of starting - ignition of the car.
