    Decent DMM for the money.

    Overall: 4.5 out of 5

    It's got the basic DMM features, and the unit I received is within calibration standards.
    I wouldn't use this on high voltages, but for 110AC, measuring DC volts in the amps I repairs etc, it works fine.
    I like the backlight and the hold feature. I only wish it has a relative function.
    I purchased this on January 7th , MCM shipped it on the 8th and it was at my door on the 15th.

    GREAT Basic Meter!

    Overall: 5 out of 5

    I bought one to keep around the shop for some basics- like checking battery voltage, testing cables, etc. Was so happy with it that I bought 2 more!

    A Good Bang for the Buck!

    Overall: 4 out of 5

    For a good price, I had reservations but, it has been performing very well with no issues so far. I am very happy with it.

    Ridiculous Value!

    Overall: 4.5 out of 5

    This is a very decent, accurate, reliable DMM that implodes the competition for value. Comparable models are 2 or 3 time the price that I know of. While replacing the battery requires removing the whole cover, I get many years of use on one 9V battery so not a big deal and it makes for a better overall seal. Great Xmas/birthday present too as who gets something this good for so little and most people can use an extra. I have one in the car, upstairs downstairs, etc so
    one is always handy. When these are on sale, it almost like stealing.

    Compact Digital Multimeter

    Overall: 4.5 out of 5

    I use this everyday since purchasing it and have had no issues. It is a good little meter for the price and appears to be plenty accurate.

    Review Product 2,000 Count 3-1/2 Digit Multimeter DMM

    Overall: 5 out of 5

    Bought it when it was on sale. Inexpensively made, but worth the cost. The only very minor criticism is that one must remove the entire back of case to install 9V battery. It could have been designed such that the battery compartment had its own smaller access door. Still, battery installation was not a big deal.

    Great addition to your tool bag!

    Overall: 5 out of 5

    If you just need a simple meter, this is a great value!

    Good DMM

    Overall: 4.5 out of 5

    Great meter for the money. I've gotten good measurements with this for several years now. DC voltage down to a couple mV or so, AC voltage, resistance, capacitance, amperage. Diode check seems to work, but the info in the display doesn't seem consistent with the description in the manual.
