    Happy with quality. If you want to use it as a logging meter you'll want to defeat the auto power off. To do that, hold down the "mode" button while turning on.

    4.0 out of 5 stars It's pretty ok..
    Reviewed in the United States on October 26, 2018
    Verified Purchase
    When I was 13 I was given a multimeter through a series of unlikely events. It was a Fluke 23 (series one, i.e. no series). I'm now 45, and it just quit, so I'm replacing it. I mention this because that's a lot of "used to" to overcome, and beyond that, I've barely even used another meter in my life.

    This meter feels pretty well put together. The probes are kind of blunt, not badly but if you're trying to hit half mm surface mount pins or something, you probably want another set of probes (or clip something to these). The tips have a removable sheath covering all but a 1/8" or so of metal tip, making them much harder to actually touch something with, but even harder still to accidentally touch. It claims to be CAT-III (600v, circuit breakers, that sort of thing) with them on, otherwise CAT-II (110/220 V, outlets, lamps.. normal mains, after the breakers). I'm mostly an electronics guy (computers, handheld gadgets, phones) so I doubt I'll need to mess with distribution level CAT-III, but it's nice to have the option I suppose.

    It measures what it says it does - V/A/R/diode check+beep, auto ranges and also checks capacitance (seems to work). It has a "hold" button to freeze current measurement an a min/max to reset and/or check how high/low it's been. Neither is that super useful - very fiddly to manage to press while holding the probes, but I'm sure it could be useful. The center turn selector picks Amp and very large range (micro, mili, or 10 Amp, the last having it's own fused connection spot), volt and DC or AC(also does Hz), or Resistance (or diode, capacitance). The overloaded settings have the sub-mode selected with a mode button (Amp AC or DC, Volt AC or Hz, Resistance or Diode) which is a bit fiddly. Not too dire, but the Amp (any range) resets to AC constantly, so it's a bit annoying when working with DC and flipping between V and A. Also, the m an u range A use the same connector as V, which is ok, but there's no physical probe change, so you could switch it form high impedance (V) to essentially shorted 0 ohm (A) just by twisting the knob. So probably make sure not to change that while connected. There's a small worklight on the front, which I haven't really used, but it seems like a reasonable idea.

    The updates are a little sluggish, refreshing about 1-2x per second. That doesn't seem slow, and it really isn't that bad, but it's still a "beat" if you change something and then look at the meter - enough to kind of notice and needing to pause before trusting it's the current reading. The ranging can be 1-2 sec sometimes, sort of a double "small wait" while it zooms around M-k-blank.. number. Not enough to be seriously annoying, but it's certainly there.

    The bluetooth functionality seemed to at first not handle Android at all, but it turns out it only supports fairly modern versions. No idea which ones - all links go to the play store, which just tells you if it works on your device(s), nothing more. If if *doesn't* work on the device/devices on your logged in account, it doesn't show up in search, and the play store links vanish, to the confusion of many (including me). Trying a few various phones, I did find one that worked, I believe 5.0 (lollipop). Since Oreo is already here, that may seem plenty compatible, but keep in mind it's not like everything is always updated, and it would have been nice to at least mention (or admit once you're trying to install) the limitation. It'd also be nice to support lesser version to use "leftover" phones when in less than safe environments, but could be BLE doesn't go lower. It also doesn't seem to work with Kindle Fire, which should have all the hardware needed. It may still be possible to sideload, but it's not presenting for install w/ sideloaded Play Store.

    On top of that, the version doesn't seem to do the things the iOS version does. It has most of the things on the meter (except the twist-select in the center), plus it can log reading for a period. It's not particularly user friendly, not too bad, but certainly awkward, same sort of "touch it and I'll reset everything" vibe the meter has, making it hard to trust for more than just mirroring the meter. A better version would be nice, as would kindle support.

    All in all, it's not so bad. I really want to like it, and I think I might. All the little details add up to feel more like a slightly lower-end all-digital gizmo than a strong, mostly physical device. But none are dealbreakers, and it's not really fair to compare it to my very old but very high-end fluke, so unless any of that just sound like the exact thing you're trying to avoid, I'd still recommend it.

    Great value, I use this meter daily with small voltages and every so often I ram it into a 480 three phase box at work. Hey I'm still here so the isolation must be good. Seriously the ONLY annoying thing about this meter is making a battery change who ever engineered that REALLY needs to do it a few times.... Its a great meter you will not regret picking one up.

    4.0 out of 5 stars Just a week after purchase, saved me a call to an electrician
    Reviewed in the United States on December 27, 2016
    Vine Customer Review of Free Product( What's this? )
    You wouldn't believe it, but a couple weeks after getting this multimeter the power went out in several of our living room outlets. It was great to be able to troubleshoot this myself, without having to engage an electrician. This multimeter has way more functions than I would ever use, or even know how to use, but it does the basics just fine. I primarily use it for DC power, when working on my motorcycles and installing new electrical components. I also had my first experience with AC power when using it in our outlets. I was able to locate the dead outlet, snug up the wires, and fix the problem. Such a satisfying feeling!
    The multimeter is easy to ready, intuitive to operate, and feels like it can survive some bumps and falls without breaking. I haven't used the phone app, so I can't really review that functionality. I don't see myself ever using it, either, since it means there would be just another thing to fiddle with when trying to get the job done. In terms of weaknesses, there is really only one: the probes. Unfortunately, they won't stay in the outlet on their own, because they are very short and stubby. That can make it tricky to hold everything in place, and it helps to have an extra person around. It would have been nice is they would have made the probes long enough to stick in the outlet and stay without holding them. Even with this minor annoyance, I am very satisfied with it and the functions.

    Functions great as basic multimeter. What justified the price tag of this over other multimeter for me is bluetooth/logging (via phone app). If the app wasn't so horrible, I could easy give this 4* overall but app constantly freezes with long recordings/logs. I have managed to get it some work sampling at 5s rather than default 0.5s...

    I used this (model 16040T) to test AC voltage on a car alternator. The readings are the same as my $7, non-trueRMS multimeter. To make sure, I tested both brand new car and the car I am troubleshooting. No difference. Extremely disappointed.
    UPDATE: It is the auto ranging that’s bad. It couldn’t fix on a correct range to be able to present a stable AC RMS value.
