I buy instruments for accuracy, repeatability, reliability and
durability. Measurements can directly affect the quality of what
is being designed and manufactured. I believe high quality
calipers are worth the cost and have bought Mitutoyo and starret.
Personally the cost of new is beyond what I can reasonably spend
however there can be good finds on the used market. To each their
own

IF you were trying to measure down to 10 thousandths inch
increments sure. But for standard down to a thousandth... The cheap
stuff will give the same reading repeatably, every time.

Same thing for cheap electronic scales. The $15 El Cheapo that
resolves to hundredths of a gram is just as good as the $500 model.
Some even do parts counting and still fall in at below a $20.

A cheap yardstick and a nice steel rule both work fine for most
things. If you want to make fine resolution cut lengths, you use the
steel tape that resolves to 32nd inch marks. Otherwise the yardstick
works fine and they are a dime each. There was a time when they were
a dime a dozen.

Knowing what work for a given job matters. If I am doing basic
voltage readings on an AC line branch, I am NOT going to be putting
my $600 Fluke at risk. I can use the Harbor Freight $25 meter all
day long.

Got it and measures very good (I had a good quality vernier as
reference)

Amazing at that low cost


afaict the biggest issue people have with cheap calipers is that
they don't last very long on battery

it's not really a high precision instrument anyway, there's a
reason they are also called very-nears


I saw this today on another group. The poster was complaining
about
short battery life of Harbor Freight meters and bought this
instead.

But I haven't got an answer about battery life on that unit from
him yet, it has only been a few hours.
The Aliexpress uses an LR44 rated 120mah and the Amazon one uses
a
CR2032 Rated 235mah. And for whatever it means, The LR44 is 1.5V
and the CR2032 is 3V.

I place my calipers in their case when I am not using them. 5
seconds of my time to remove the battery and place it in its cutout
is zero cost. I am not bothered by the additional labor or lack or
ready access.

+++ My HF caliper is many years old, still uses the original
battery because I do exactly what you said.

Another way is to make a thin film strip to place in the battery
pocket to "turn it off".

laptops, battery operated drills, keep their battery in. they are
made for it. the caliper folks simply want to take up less space or
cannot be bothered by installing a watchdog like those in small
weighing scales.

When I put my laptop away, I pull the USB Xcvr out and turn off the
mouse, and it stows the xcvr in its base. Every day. I would have
gone through a couple batteries this last year otherwise. No big
deal, but I am 100% a small carbon footprint guy.

Maybe you could use alkaline batteries instead of carbon zinc then?

HA HA HA

Small carbon footprint means NO carbon zinc.

I only see them if I peruse the Harbor Frieght store because rat
shack does not exist any more. There are actual battery stores in
Michigan... small batteries not car batteries.

Feed china your money?

Sure. For a US product, that would just come from the same Chinese factory (typical OEM sold seperately)

Those on Amazon are only like $9.

so 4 times higher cost

> How much was your shipping?

Zero

I do not trust China sites for online buying.

I do, have done a lot of purchased in China.

They're Chinese. There is no US association whatsoever.

Perhaps you need a remedial math course.

I meant that if you buy an "american" made product, chances are that it was made in China (like Apple and their "Designed in US" notices on the products)

Those on Amazon are only like $9.

Not really. I bought it for 2.79 USD at Christmas sale. The price you see now is standard price

2.79 x 4 is not 9.

So yes.... really.
