    It does not have a backlit screen.

    It does not automatically measure AC/DC (whether when measuring voltage or current) ... And it does not have memory to remember the last setting you had it on when you last closed it. Every time you open it, it measures DC and you have to press SELECT to switch to AC.

    *You cannot measure currents with the terminals (by connecting it in series), it only measures inductive currents.

    At least it has automatic scale when measuring voltage or resistance, and with the middle button you can also change the scale yourself.

    It does not measure capacitors.*

    *It measures frequency but has a problem, sometimes it shows the values correctly and sometimes it constantly changes values.

    *It takes almost 2 seconds to turn on.

    The terminals are each 1.05m (the cables alone are 90cm)

    It is convenient that the terminals are one above the other, and not left to right (convenient when packing it up)

    You can change the measurement mode with one hand (from the sides)

    The values are updated quickly (probably every 0.1sec)

    The sound is heard directly and clearly when performing continuity check. But you have to press select first.

    *When you forget to turn it off, after about 10 minutes it makes a warning sound to shut it down, and if you leave it after a few minutes it shuts down by itself to save the battery for no reason. I don't think it consumes much battery though. A 9V battery will probably last for years. The screen does not show the battery percentage. *The battery is included (at least mine had it)

    Weight: 280g including the terminals.. so let's say 300g with the case.
    Height: 21cm

    For its price, it is good. I bought this one because it also measures DC currents, if it breaks after some time I will update the review.

    Overall, it is what I had read.
    Very user-friendly and convenient.
    The only disadvantage is in the DC currents.
    I have a deviation of up to 0.3 A in measurements up to 20A. Higher than that, the deviation is not bothersome.
    I think it is a decent choice for non-critical results.
