I received my EX-420 and never expected to receive such a great piece of test gear. I have over most of my life been a John Fluke or Techtronics gurue and only wanted this instrument to replace an old Fluke for my take and run electronics bag. Was I ever surprised at the quality and accuracy of all phases of this instrument. Wouldn't be a bit afraid to add it to my benchtop instrumentation. It far exceeded my wildest expectations. The Amazon seller who supplied this item was wonderful too with very fast shipment and I would rate them with a very +++AAA. Do't know why anyone would look no further.

Great meter for the money! It works without complaint, and does everything that I ask. This is my first real auto-ranging meter, coming from a world of Chinese cheap meters. My only real complaint (a minor one) is that the backlight is a little uneven. Other than that, this seems to be a meter that I can trust. The only thing that it is missing is the bar graph -- but you can find that in a higher-end model.

Style Name: Standard Verified Purchase
Unit defective out of the box. The continuity buzzer sounded like it had a short circuit. Sending this one back for replacement. I also (like other reviewer) was surprised the battery was installed and functional with no power blocking strip installed. No instructions on how to access battery compartment.

I was torn between spending a lot on a Fluke and this DMM, but decided I would never need the quality of the Fluke - hope I made the right decision and that the replacement unit will work OK.

I will edit this review when new meter received.

Edit Jan/2015: I received the replacement unit but it also had the same problem. On closer examination (not believing two consecutive could be bad) I inspected the leads. On the lead ends that connect to the meter there are factory installed plastic tips (not the protective caps). I suspected poor contact with the meter's female connections. I connected my old leads from the meter this Extech replaced and the problem was not there. I contacted Extech tech support and was told there was a protective coating on the tips to prevent corrosion in storage (why was this not noted in instructions). The tech suggested I clean the test side tips with acetone. After doing this the problem got better but the leads still do not perform as well as my old leads. I still suspect a problem with the male contacts not being spread enough for really good contact with the female plug in the meter.

Working now with Extech to see if I can fully resolve the issue to my satisfaction after Extech product support replied to my review - which shows good product service.

Edit Jan9/15: Just got an email response from Product Manager. We'll see what happens.

Edit Jan 23/15: Extech sent new leads which fixed the problem. So far customer service response has been good. I upgraded the number of stars to 4 and will reassess as I work with this meter.

Hello Bill,
My apologies that you have had to deal with an out of box failure with an EX420. I understand the frustration that accompanies such an experience. Although I see you are waiting on a replacement, I am happy to arrange a tested unit for you. You can reach me at feedback@extech.com. Please let me know if there are any problems with the replacement unit that is on its way to you, and if I can assist further.

Best Regards,
Jamie Cohen

As I opened the clamshell package it seemed that it may have been opened before because of how easy it was to open. The next strange thing was the pre-installed 9V battery which had no current blocking tabs. that meant the meter had shipped in the semi-on state. That's unusual for Electronic Equipment. Finally the Selector switch would only work for AC and DC voltage. I could not get the select button to choose anything else such as Resistance, Continuity, or any other function. I have returned it and won't plan on buying an Extech meter in the future. I am always glad that Amazon takes care of their customers with a reliable return service. Stuff happens but this time it just plain didn't work.
