How to spot fake Mitutoyo calipers

(1/9) > >>

HwAoRrDk:
Very interesting video about fake Mitutoyo digital calipers.



It's a mystery to me how whoever is producing these fakes fails to notice or get right some of the most basic things - like black stripes on the packaging versus grey? I mean I can understand that perhaps a native Chinese speaker might not understand the nuances of latin typography (kerning, proportions, etc.), but basic shapes and colours? :palm:

He says that there's nothing particularly wrong with these fakes (apart from the higher power consumption and lower battery life) functionality- or quality-wise in terms of their ability to do the job, but at the end of the day, if you're happy with these things, you might as well be buying a no-name brand for a lower price, rather than a fake that is overpriced for what it is.

Which reminds me, this week in Lidl UK there are quite decent digital calipers for £9.99.

MarkF:
'Big Clive' did a teardown of cheap carbon fiber eBay calipers for £5.
Apparently, they are not too bad.  It looks like they can still be found.

This is not "decent". This is a typical Chinese junk. There are hundreds of those sold under various names, but they all are universally bad.

iGaging  Absolute Origin are much cheaper compared to Mitutoyo, but they have very similar feel and performance.

The carbon ones are really good for what they are. I have a pair of those for quick measurement. Their accuracy is usually good enough for electronics-related stuff. I would not use them as the main tool though.

In what way? They are very accurate and some are smooth and work well. Only downside is the short battery life (<1 year on SR44). I've used 4 of the cheapies.
For $15 I think its a fair deal.
For $70 or whatever people are paying for a few pieces of paper that say "Mitutoyo" of course its a rip off

Yes igaging is one of the best calipers for the money once you go above the $15 mark. $40 is well worth it if you use your calipers more than a few times a year.
