MM300

I had ordered a less expensive meter, and the lead terminals that plug into the unit fell apart. I was careful with it but that didn't matter. I have had this Klein meter for 2 years now and it never fails me! Would buy again.

This is my review of the following items: Klein Tools model MM300 digital multimeter PLEASE NOTE: I am NOT Gough Lui or Dave Jones at EEVBlog. Therefore, I do not have access to thousands of dollars of expensive test gear to fully validate the usability or reliability of these products. This review is from the viewpoint of the average buyer/user of above listed products. It is not an exhaustive test and there will be some information provided that's still preliminary due to insufficient testing time alloted. This will be carefully noted in each item's review and preliminary information will be updated as time allows. GENERAL REVIEW - This multimeter is quite the respectable lot. It is VERY sturdily built and passes the "twist test" with gusto. The leads are very flexible and the connectors plug into the meter very snugly and won't fall out easily. The tips of the probes are sharp, but not so sharp that they'd go right through you easily. Also, the manual range switch is very stout and tight, with a very firm click that's reassuring to the touch. If there are any flaws with this meter, it would probably be the very long delay that you wait for the buzzer to sound when touching the probes together in continuity mode. I've seen meters reviewed by the likes of EEVBlog and The Defpom that are faster acting than this one, but that may be due to things outside my control including dirty probes. However, it registers voltage and resistance very quickly and the 1.5-9 volt battery test is useful. I am confident that this meter will last a long time with the proper care. The only other issue I can find, aside from the tardy response time in continuity mode, is Klein Tools' choice to use AAA cells instead of AA cells to power this meter, but I suppose that's a case of "You get what you pay for". I am not able to test it, but I'm certain this meter will survive 600 volts without issue. How many cheap sub-$20 Chinese meters do you know that can do that? CLOSING THOUGHTS - To summarize, the Klein Tools MM300 is a competent and very well-built meter that also accomplishes this without draining your wallet. It does have its limitations like a slow response to continuity checks and limited battery life owing to its use of AAA cells instead of AA cells. But overall, I'd recommend this meter for the individual who is just starting out in his/her first electronics project or the intrepid do-it-yourself home handyman who just needs a basic no-frills multimeter that's also reasonably inexpensive, very robust and abides totally to safety codes and regulations and won't crap out after a year or two of use.

For the price, I'm surprised at how good this feels. I need something I can depend on for work, but only need it a few times a year. I had an off-brand one I purchased a couple of years ago that didn't last for more than a few uses. This was only a couple of dollars more but feels way better. I really can't review the quality yet, I've only used it once, it will take time to know how good it really is, but the fact it's a Klein and because of the feel of it, I'm sure this will last for a long time.

Still works after several months of use and pretty accurate for voltage. Cheap and survived some drops. Good value.

Very happy with how it works

I prefer an auto ranging multimeter but for something unlikely ever to see any use (hopefully), this is an affordable and sturdy multimeter that I expect will survive years of being ignored in the toolbox until there is a crisis on the road. Tested it enough to know that it does what I need in a pinch for basic automotive testing.

There is no way for more to verify the accuracy, but I'm sure it's good enough for my purposes. I use it mainly for checking circuitry and batteries in my motorhome and boat. It's easy to use and has nice long wires for testing. I prefer this manual ranging volt meter over the auto ranging.

It seems to be accurate. Features such as beeping when taking a reading and storage on the back for cords are nice.

good

E um multímetro básico e atende bem no que e projetado.

je m'en sers pour tester toutes mes opérations électriques, A ce jour 17/1/2019, il est tombé en panne. Quel est le recours ? Merci d'avance de votre retour

Excelente producto, buena calidad y de fácil manejo

I just got my Multimeter today and I'm already loving it, the little kick stand in the back is my favourite feature for sure, great rugged build quality, but from Klein I wouldn't expect any less, I'd been using a UEI meter for some time and for the cost, this definitely gives my old meter a run for it's money. $300 vs $45 and I like this $45 one more.
