$10, analog, niiiice
Ok, Pro number 1: Analog multimeters are very useful, at least to me. Digital ones are too, but sometimes it's really really nice to have the smoother, instant response and visual cues of an analog meter versus the jumpy, update-time delayed response of a digital multimeter.Number 2: Cheap analog multimeters are very useful because if you take care of them they last forever but you can also throw them in a toolbox, let them ride around in your car's console, lend them to a kid, or whatever, and they generally take a beating... and when they don't, you replace them without breaking the bank.I have two of these, and I use them for everything from testing wall sockets, to checking continuity in circuits, checking resistance to test electrical components on motorcycles, and best of all for backyard science. With two, I can put them in parallel and series on a circuit and get voltage and current at the same time. Really nice when setting up an electrolysis bath or some other backyard chemistry.Cons: I'm kind of disappointed in just HOW cheapy these are. "Back in my day" you could get a pretty good one by BK Precision or some other decent company in the $10 range; super sad that mine finally died after something like 20 years of hard use and abuse. These Gardners are bottom-tier Ali-express units that are rebranded for a lot of sellers. They feel cheap and my expectations are pretty low, but they're still fit for the purposes I listed above.

Perfect fit for me
Last time my multitester died, about 20 years ago, I bought a digital model. Hey I love high tech for many products, but in this case, I missed Old Reliable analog output. Maybe not as precise as digital, but plenty precise enough for my needs. and just a more stable readout. (One drawback on my digital multitester was the numbers fluctuated by the second--unnecessary detail). Other huge pluses with this model: it takes one AA battery, not a more expensive 9V. It's smaller and easier to carry and store than my digital multitester. It performs all the basic functions I need in testing battery strength, circuit power, and resistance. Note that if you're new to multitesters, no instructions are included in the package BUT in the name of green they link you to a website where you can download instructions. Actually, this is better, not only in the sense of being green, because most people don't RTFM especially for a product like this, but also because an electronic manual is easier to store and search by keyword. For the price, a pound-the-table buy for me.

A solid basic analog multimeter used as a "dwell meter" for an antique Morse code key
Like having a physical needle rather than digital numerals for my application. Meter placed between the contacts of an antique semi-automatic morse code key, which makes continuous "dits" when a lever is held (a metronome-like vibrating read actually closes the contacts once with each swing of the lever). The meter serves as a "dwell meter" analogous to those used on automobile engines with mechanical "points" back in the day, which allows you to accurately set what percentage of each swing the contacts are open or closed. Roughly 50% is desired. Fun application with an analog meter.It also works in the normal multi-meter functions, of course.

Digital meters are great, but may lack dependability with their dependence on ...
I bought a couple of these. I have had many multimeters. I am a EE and have been looking for a small, analog meter. Digital meters are great, but may lack dependability with their dependence on a battery. Analog meters do not require a working battery except for the resistance scale. This meter is the perfect size to keep in your car and cheap enough that you can buy several and have them where you need them. I have other analog and digital meters for precise bench measurement. It also seems to get good reviews in general. I like it and plan to get one more.Pro'sSmall size - quite compactRugged - appears to have fairly thick plastic and reviews are goodAppearance - very readable with bright white background and mulitcolor display, bright orange needleFunction - quick, responsive meter movementAdjustment - Zero adjustment for needle. Zero adjustment for ohmsCon'sRange - somewhat limited, but this IS a mini meter. You know what you are getting when you buy it. Ohms are limited to just the 1K scale. As mentioned in one other review, a lower DC scale, perhaps a 3V scale would certainly be better than a 250VDC scale. You will likely never measure a DC voltage over the 150V range (provided) but you certainly will be measuring common batteries, which may be 1.5V. You have to measure a AA battery on the 10V scale and you lose a bit of resolution here over the missing 3V scale.Marking error - This is a goofy error that shows carelessness in the design. The scale selector switch shows 250 V scales for both DC and AC. There IS NO 250V scale on the meter face! There is 10, 50, 150, 300 on the meter face. So what scale do you use to view the so-called 250V scale. Turns out that 250V on the selector switch goes with 300 on the meter face and you probably would have guessed that but no way to know without confirming. Generally the voltage selected on the rotary switch tells the voltage for full scale deflection, but not in this case! I had to determine this by noting that setting to 250V and reading a 120VAC line displays 120 on the 300 scale. I have never seen a meter with this error. It is something I would expect to see on a Chinese Harbor Freight product. Not that this meter isn't Chinese. That's the reason we can get it for $12.So, actually a nice little meter with generally useful scales. I'm docking a point, though for the messed up selector labeling and the fact that they could have easily put a useful 3VDC range on there instead of a 300VDC range.In fact, I may open mine up and change the resistor go give me a modification on that range. If I do that, I'll post the hack for those interested. Hope they use through hole components and not SMD.Cheers . . . DJI docked it one star for

Simple is Better
I have a couple electronic meters. I hate them. I wanted to back to a simpler time, and get this old style analog meter, like the one I bought 50 years ago to build my first stereo. What a great decision. I love it. Don't hesitate to purchase this meter, it's accurate, looks good, easy to use, works great. Sometimes simple is just better.

nice to have in an emergency
I keep one in my truck with no battery in it (so the battery won't leak in it).if all you need is to check voltages, a battery is not needed.voltage is not super accurate, can be off by 5% on some settings, but works fine to see if proper voltage is present.
