As an electrical engineer with over 40 years of experience I was not expecting much from this meter. I just wanted a very basic analog meter. I had no need for a high degree of accuracy - I simply wanted a basic analog meter. Analog meters are quite useful when adjusting a circuit that goes from low to high and back to low again or visa versa. A digital meter gets very confused as voltages change rapidly. With a digital meter it is hard to determine the high or low (null) point of any circuit. Practical examples of this are in throttle position sensors (automobiles) or in other sensors (alarms, etc). There are many other examples where a circuit goes from high to low or low to high and an inexpensive analog meter is often far superior to the best digitals!!!! Needless to say an oscilloscope is best.
Nevertheless this meter (despite my very low expectations) was one of the worst electronic products I've ever encountered.
One major flaw in this meter are its scales. For example: As a quick test of this meter I decided to test my home's AC outlets. I selected the 300 AC volt range (my only other choices would have been 50 volts or 10 volts). So 300 volts AC was the ONLY appropriate range to test the AC voltage in my house. Now remember, I've been doing this type of measurement for over 40 years and I've also worked with analog meters for that length of time. Since home voltage is roughly 120 volts and the range I selected on the meter was 0 to 300 volts - I expected the needle to move slightly less than half of its full scale when I tested an AC outlet (a voltage of 150 volts would have produced a true half scale reading). What I saw was just a slight deflection of the meter. At first I thought my probes were not making a good contact (they were) and then I thought the meter was broken. I was wrong on both counts.
If one looks VERY carefully at the meter's face you will discover a scale of 0 to 300 for both ACV/DCV that only uses less than half of the full deflection of the meter. I have NEVER/EVER seen such a bizarre scale or implementation. The multi-language one page "manual" offered no help or guidance.
I'd strongly discourage the purchase of this meter by any hobbyist, amateur or intermediate user. Engineers need to be aware of the bizarre scales employed and also be aware that what appears to be a mirrored scale in the pictures is a crude piece of foil with very poor reflective properties and thus useless as a mirrored scale.
Update - an hour after this meter arrived it suddenly stopped working. It is on its way back to Amazon as I type this but remember my complaint is about the poor design and not necessarily about reliability, since the failure of a single unit does not imply overall quality control issues yet it can be a warning

The Extech so far has been a great meter in a case protected with a rubber holster. I like the analog display compared to a previous digital display that I have had.

An excellent analog meter. I have had it on my bench now for over a year and it still performs flawlessly. Has a battery test function for any 1.5 or 9v battery. Quick deflection , long sweep meter to help with accurate measurments. I prefer analog meters over digital ones, as you can see minor quick electrical changes with an analog that you don't with the digital counterparts. The meter is bigger than pocket size, unless you have big pockets. It is 6.5" Tall by 3.5" wide.
It comes with a rubber holster to help keep it up with hard daily use. For the cost, it is an excellent "throw in the box" meter to have and I highly recommend it.
