TEST METER
I was thinking about buying the equal to the Fluke meter, but ending choosing the Klein, replacing an older Fluke. Price, durable, dependability and glad I choose the new Klein.

    Tough, Compact, and Reliable
    This meter has been bouncing around the bottom of my bucket of tools for around ten years. It is used nearly every day as part of my diagnostic kit checking AC/Furnace, commercial refrigeration and solar energy control systems. Tough, dependable, and accurate. Also discontinued but replaced with another great Klein product. It's a small meter, so if you test a lot of really big capacitors it can be a bit slow. I have no relatioship with Klein, just a long time appreciative customer. btw I enjoy solo trans-oceanic boating like California to Hawaii. Sailboat or Powerboat, this little meter is always along, and has never disappointed me.

    Durable
    I bought my multimeter several years ago and this thing just will not die! It faithfully checks voltage even after my apprentices have dipped them out of lifts. This wasn't the first Klein tool I've owned, but I guarantee it will not be the last!

    Made in China
    Works as advertised. Was expecting it to be made in USA but no, it was made in China. So much for all of the hype from Klein about being a US manufacturer.

    Nice meter for the money
    Walmart delivered ahead of scheduled date. The meter works very well and is simple to use. The semi-soft protective casing will help absorb shock if dropped. Does everything a Fluke does at less than half the price, but I'm not a professional so it won't get used every day.

    Klein Tools multimeter MM400
    I recently purchased this multimeter at Walmart.com and am very pleased with the product, not only does it do all the standard tests expected of the average meter, but it has quite a few hidden gems in its bag of tricks as well, it's autoranging function is nice and the blue back lit display is awesome and easy to use in low light conditions, and if you're inclined to use it for automotive applications, not only does it include a Very accurate temperature testing cable, (albeit a little slow to settle in to the max or min temperature) it's also got a extra bonus of being able to measure duty cycles and frequency output, and these are features usually only found in way more expensive and rediculously overpriced meters such as Fluke brand, that are 3 to 5 times the price as this little gem, bottom line is that if you're interested in a better than average multimeter and don't want a dollar store piece of junk, this is a solid buy, especially at the Walmart price point, btw buy the Zip up soft case, and the hands free hanger magnet as well, I bought both here as well, and am glad I did , the magnetic hanger is a bit pricey but it's a really convenient way to use the meter on cars and electrician applications and it will save your meter from crashing into the concrete floor, and the soft case is a steal for the price!

    This is a quality meter at a very good price. Klein doesn't make junk. Storage bag is also available for this meter.
