The fact that Mitutoyo draws ~15-25 times less standby current is enough of a deciding factor for me alone. Steady use over 5 years with quality batteries probably narrows the price gap significantly. In my experience the grind quality and hardness of the jaws is also far superior, and that is probably where a lot of the manufacturing cost comes in (not to mention Japanese quality assurance). The cheap ones are OK for a beater/woodworking pair, but I just prefer to support quality companies making nice tools.

I have an 8" Neiko I use for work that I really love. The case really is great. I work in a manufacturing environment and sometimes I don't want to carry around a huge clipboard or toolbox on the factory floor, so I use that long slot to hold a pencil and tuck a tiny notepad into the lid.

Great timing. I’ve had a Husky brand digital caliper (from Home Depot for about $30, if I remember right) for quite a few years now. It was a huge upgrade from the basic-basic caliper I had prior and I use it all the time. I’ve done my best to take care of it- I store it in the case and I’ve dropped it maybe once. But, recently the battery cover has become loose and it likes to randomly reset itself while measuring something, unless I handle it insanely delicately and/or hold the battery cover down while using it, which isn’t always convenient and doesn’t always work. I’ve tweaked the battery contacts, I’ve used a bit of dielectric grease on the contacts, I’ve even taped the damn cover down with various types of tape, but nothing works well long-term, so it’s about time I buy a new one. Edit: I really like the Qfun. I like the bigger display and, honestly, like that it uses a cr2032 battery. I have a bunch of cr2032 devices, so I have a ton of extra batteries on hand, and even have some rechargeable cr2032 cells, so the extra power draw (at least initially) isn’t too concerning. Plus, the IP rating is interesting. I don’t recall ever needing to use my calipers in wet/dusty conditions, but it’s kind of nice to know it’s there if I ever need it.

At home I have a NEIKO I really like, glad to see it made the top 3 of your options here. At work where they didn't care what I spent I got a solar powered Mitotoyo which is like $230 but literally never ever needs a battery swap. It also has no on/off button, its just on whenever the case is open and it's exposed to light. Kinda weird that it basically needs to live in the dark to turn off but it definitely works and feels great.

The mitutoyo is my favorite , I have a knockoff Mitutoyo also, and it works surprisingly well, but the fit and finish isn’t up to par, and the battery runs out much faster . great info , thanks !

In the comparable brief time of owning the BW I had to swap out the Batteries like 4-5 times despite the Caliper having an auto shutoff function which obviously always happened at times when I couldn't get a replacement battery sending me into a rage. I'm now in my 2nd year of the Mitutoyo - which will remain on until you turn em off ( which I _constantly_ forget to do thanks to the BW 😑 ) - and I'm still on the 1st battery it shipped with 🥰

Interestingly, I recently got the cheapest Tool Shop brand digital caliper from Menards and that one draws only 0.5 micro Amp in the OFF state, which is perfect.

Gotcha, I can always do a follow-up.

I have had an Insize digital caliper (respected Indian manufacturer sold by tooling suppliers for professionals) but they have gone defective after seeral years. I like the review conducted here although being in the UK I cannot relate to any bar the Mitutoyu. The close relationship of the power consumption data (and many thanks for including this important data set) leads me to conclude that the circuit in all $20-30-ish calipers is essentially the same - perhaps some are the same. I think that perhaps the Insize is the same because I was always (it seemed to me) having to change the battery. I have thus decided that I am going to splurge £140 on a pair of Mitutoyu Dial Calipers with 1mm/rev and 0.01mm resolution. My model engineering club has Mitutoyu dial calipers and they are a joy to use - AND THEY NEVER NEED A BATTERY!!!

This is a pretty good review. i still have a mechanical caliper set that I inherited from my grandfather. And for what little I use it, never bothered with a digital set.

I think what makes the difference with these cheaper calipers (especially the harbor freight brands) is the dies they use in the manufacturing process. The cheaper calipers can be very usable for most people, if you're a machinist you probably want something better. But... as they create millions of units of these, those dies wear out. If you can buy one of these cheaper brands when they're first introduced, you're probably going to get a decent tool. But after the unit has been out for a few years, those dies get trashed and because they're cheap, they don't order new dies until the old dies are unusable. So if the model has been out for a few years, the quality goes way way down. So whenever I see a new tool like this show up at Harbor Freight, I snap it up. But I know, in a year or two, that same model will likely be junk even though the original was decent.

I'm not sure there is any stamping here. These are all most likely ground. You may be right on some other tools, but these aren't just stamped steel or die cast.

There are a couple of technologies for measuring encoders, their combination gives the main differences in electronics plus the quality of manufacturing of the mechanical part. this together defines the caliper. 1. glass base or fiberglass (influence of temperature, glass is more stable) 2. absolute counting or incremental. the latter has restrictions on movement speed (about 3m/s) and usually there is no complete shutdown, only the screen. and when turned on, it also checks the positions more often, which also results in increased energy consumption. 3. capacitive or inductive sensor. only induction does not react to liquids (IP76 ). The Chinese have had absolute capacitive ones for a long time and not so long ago they had induction ones, as soon as absolute induction ones appear, then in terms of electronics there will be no fundamental differences with brands. I have a Chinese TERMA with an absolute capacitive line, current consumption is 24 μA on and 1.5 μA off, which with its 2032 batteries is a year of operation and 15 years when turned off :) a check that will easily show the difference in manufacturing accuracy: tighten the fixing screw until it is not fully stif and move the carriage along the entire length of the caliper; if the force everywhere is the same, then it’s good, but if it sticks at all, then it’s bad.

The only thing I would have liked to see is how often do you need to zero them out? For instance, slide it back and forth a few times and then when closed, how close to 0 is it still?

The igaging calipers seem to be around the expected reading, give or take 0.01mm or so. So accuracy is plausibly reasonable. I believe the company also sell inexpensive scales for CNC machines?

Of all the details from various calipers, auto off is one that is really missed when not there, and that is functionality that is missing from certain higher models as well as lower models that I cant believe is scrimped on!

Low-end calipers with relative encoders never actually turn off - the on/off button just toggles the screen, but doesn't meaningfully reduce power consumption. Some cheap calipers do actually switch off, but you need to re-zero them every time you turn them on. For the most part, auto-off is just a mildly annoying gimmick. As shown in the video, the Mitutoyos draw 3x less current when switched on than any of the other calipers when they're switched "off". Some of the less expensive brands do offer calipers with absolute encoders, but they aren't all that much cheaper than Mitutoyos. If you're concerned about battery life, my suggestion would be to either buy once and cry once with the Mitutoyos, or go for calipers with a CR2032 and buy a cheap bulk pack of cells. Calipers that run on LR44s will last vastly longer with SR44s because of the flatter voltage curve. Failing that, dial calipers have no batteries to go flat.

How long do the cells last on these cheapo units anyhow? I am guessing a few weeks?

My Mitutoyo calipers are 20+ YEARS old,,, still as accurate as day 1. Buy once, cry once.

Fair, but my Neikos are almost 10 years old and just fine as well. I just don't think digital calipers are really all THAT challenging to make, so I'm not sure the extra cost for the Mitutoyos is really worth it for most people.

Everyone is mentioning the iGauging brand off Amazonia so… I’ll mention them too!: They ARE very nice finish. Surprisingly smooth action for the price ($33-$40 for the EZcal. class of iGauging calipers. I ordered the 4” version as I seldom measure out beyond 3 or 4 inches so why carry around extra anything!? On that note I’ve decided to return them for a couple reasons: 1. The 4” caliper is less comfortable in the hand as soon as you measure out 2 or more inches, my hand hold simply runs out of comfortable holding room and the bottom of my palm ends up pressing against the depth gauge bar! 2. The tips of the main (outside measuring) jaws points are off center! The tips are SLIGHTLY different, one tip fatter than the other. That being said they close perfectly and hit zero literally EVERY time. 3. I HATE HATE HATE the battery tray. When closed it does NOT seat flat and flush against the top of the scream housing and it drives me nuts. It LOOKS cheap! They should close with a firm, flush and and nearly audible snap for secure closure. In conclusion I feel I may be splitting hairs and may be showing obsessive compulsive tendencies but they are annoying little things that ultimately added up to my decision to return them. BUTT! For all intensive purposes the 4” and the 6” seem to be very good quality and do exactly what they’re designed to do and will serve their owners well. I also have a set of the digital Harbor Freight Pittsburgh 6” and they were just as accurate within half a thou! They are not nearly as smooth as the iGauging EZcal’s but they measured up the same! If I’m measuring and scratching I’m using these! And they’ve always worked. I’m guessing the “Pitts” brand can be disassembled and properly cleaned and they’d be a lot smoother. So, if youre making a living with your calipers then sure, pony up the bones for the Mitutoyo noize makers of some Starrett action mess! For everything else iGauging, “Pitts”, etc. will do the job easily within a thou. So, go with what’s comfortable!

Unless you are going to go with something highly accurate like Mitutoyo, just get some for @$20

when the cheap calipers get low on battery they will give out bad readings the mitutoyo has a battery indicator, but will still give good readings. also at 4:00 the mitutoyo does reads in 1/2 thousands. all the digits are the same size it's less confusing like that. idk how you got confused. to me the ones with different sized digits just belong in the trash. so unpleasant to read the screen.

No mention of the Mitutoyo’s absolute measurement? If the battery is low or you move too quickly, many other digital calipers will lose steps and can’t be relied upon. Do any of the other calipers use the same principle as the Mitutoyo? That why I watched your video, and likewise why you’re getting a thumbs down from me.

I've heard that from a few people and haven't experienced that myself. I went and tested the others and none of them do that. So it's not something I'm familiar with or can replicate. Maybe significantly older calipers experience that?

I've often wondered why I can't buy USB rechargeable calipers. It seems like such an obvious idea to me.

cost and size is my guess. 100mah of lithium ion batt would add something like $10 to $15 to the build cost, plus the charging circuit. And would be double to triple the size.

@@KevinSatterthwaite surely that estimate is a bit high. I regularly buy 2000+mah lithium ion cells for under $10, and basic TP4056 chargers can be had for cents on aliexpress. I reckon it would add closer to $5 extra if that; a premium I would happily pay to avoid dealing with constant battery replacement and having to make sure I have spare coin cells handy at all times.

​@@KevinSatterthwaite I wouldn't actually use a 2000+mah cell in a pair of calipers. It was just a price reference. A little ~300mah pouch cell would work pretty great; the sort of thing they used to use in iPod Shuffles. There are also coin-shaped rechargable cells used in true wireless earphones which can hold about the same amount of energy as an LR44. Smartwatch battery could be a good option too.

Honestly, I like nice thick callipers. It just makes it easier to make it perfectly flat by a c***hair to what I'm measuring, (if what I'm measuring is close enough to "true/flat". Other than that? Of course, smooth threads and zero "play", combined with smooth travel along the rail make up the rest of what I call good'n'uff for the women I go with.😉🤷‍♂️ Thanks for the vid bud.

Huh, must be backordered or something. They tend to do what when discouraging new orders.

You missed consideration of durability and usability (size of head to access workpieces). The large display of the Qfun is useless, and if it's glass-based like some others I've had also very fragile. I've broken the large display on a pair that looks to that with a light accidental tap against a lathe chuck. You don't need a big display - it just needs to be large enough to be read easily. A compact unit is also more convenient when taking measurements of mounted workpieces and again, the Qfun is way bigger than it needs to be. So I don't agree with your conclusions at all.
