Boltr: calipers. How bad can ten dollar digital calipers be? Take an insider's look at the differences between cheap Chinese calipers and high quality Japanese ones. Sparkfun's Hung Lo brand versus Mitutoyo versus your wallet.
These are the bargain basement calipers that Harbor Freight, Princess Auto, KBC, Sears, Home Depot, Lowes, Canadian Tire are selling. Do they hit the "minimum viable tooling" requirements?
Is it actually cheaper to buy quality tools?
I'll also give you a few tips on how to improve the quality of cheap calipers.

I did a follow up on the battery consumption. It's shockingly bad!

And another follow up on temperature compensation. Equally terrible.

its 8 years later. do you still read all the comments hhhhmmmmm?
As an engineer, you match the tool to the job. If your job requires high level accuracy, then use the $150 models. Both units will be destroyed if you drop them, so there's no reason to blindly buy the $150 unit just because it's technically better. There will always be a place for cheap tools and the user needs to make that decision on a case by case basis.
although its a shockingly bad device inside.. it still doing its job well for 10 bucks.. for a lot of people an accuracy of 0.5T is way above what any tool is capable doing in a home shop...
I have the exact same set in my toolbox at work, they are my "loaners" When someone wants to borrow a set of calipers I throw them the cheapo set. They always come back because they are not worth stealing, and they are crappy enough to scare some people from borrowing my tools. I have an extra crappy set of socket head wrenches to loan out too. And if you borrow a screwdriver from me, it will be bent AND rounded off.
Ahhh, those are just wood worker callipers. The "give" is to allow for the natural expansion and contraction of organic materials.
what do you expect for ten dollars!? you get what you pay for ... and for you over there (I live in Europe) it's good enough! you do not have metric ... so do not talk about precision
It's 5 years later. Do you still read ALL of the comments?
The Japanese calliper is superior because it is forged from steel that is folded 1000 times. Mendeleev himself discovered all the elements by measuring them with glorious Japanese callipers.
At the machine shop I work at, I'm responsible for checking all the measuring tools in the shop every 6 months. What I can tell you it's cheap calipers may be within .001 when new but typically only last a few years before they start to generate an ever increasing error. On the other end of the spectrum there are numerous Mitutoyo calipers in our shop that are 15+ years old that still measure within .001. It's the quality out of the box and the long term accuracy that you're paying for.
$150 vs $10 and it's nearly as accurate? do me a flavour. Its amazing the lengths you go to to defend your initial purchase. (Methinks he doth protest too much). Personally I don't need to measure that many things better than with a tape measure, so I watched the video with a rye smile upon my face. Just dragged one that I bought 3 years ago out of the cupboard and it works fine though have to say that I think I've used it twice since I bought it . So just remember the 90-10 law and ensure you spend 90% of your money on things you use 10% of the time! That's the way to get real value!
Who buys a $10 tool and expects the same results as a $150 tool?
Here is the best use for the $10 calipers:
When i was 18 i was in a machining trade school and my first week someome gave me a pair of mitutoyo calipers. Ive had them for 7 years and i still use them accurately.
I've got both. Cheapos work great for general woodworking, scribing lines (can't even imagine doing that with my nice set), finding center lines, etc... Not for reliably precise work in metal. Much of my use of calipers doesn't even depend on the exact measured distance - but work great to transfer distances from one part to another (usually using the lock screw) feature. They have their place in doing things the Mitutoyos shouldn't be doing.
It’s a $10, digital wing nut wrench!
Watching this as I look at my calipers that are sitting on my desk; Seeing that they are the $10 ones; feeling bad.
I own a small engineering company and i use the mitutoyo instruments for all the important jobs.
The 10 buck ones have done every nicely for my RC hobby and are still going strong after 8yrs.
If you are really concerned about accuracy and repeatability, spend the money and buy micrometers.
You removed the self-lapping compound! Ohh-no...
