Mitutoyo 500-196-30 Advanced Onsite Sensor (AOS) Absolute Scale Digital Caliper, 0 to 6/0 to 150mm Measuring Range, 0.0005/0.01mm Resolution, LCD

Its already a given that Mitutoyo is of the highest quality right alongside Starrett. So much so that the USA is getting flooded with overseas knock offs of the Mitutoyo Calipers. Amazon and a few other reputable Mitutoyo sellers are your safest place to buy them. But steer clear of eBay! There is about a dozen YouTube videos as of this writing, that can help you to verify if yours is genuine I was happy to determine that the one I purchased here on Amazon is indeed Authentic. Be careful out there, otherwise you could end up paying well over $100 dollars for a $10 dollar knock off.

First let me say that like other reviews here I did my homework and checked that my calipers were genuine. The mitutoyo tech support stated that Amazon is an authorized distributor and my calipers were authentic. If you buy from another seller on amazon buyer beware. All the other things checked out, fancy japanese paper, crisp packaging, no battery installed, high quality build. Also, the genuine calipers have a qr code that contains the model and serial numbers. They should match. As for using the calipers themselves. They are great. Checked accuracy vs my micrometer and they were spot on. Display is easy to read. Like most calipers they are easy to use, nothing special. Dont waste your money on junk, buy real calipers and dont regret it.

I went with a 35$ digital caliper initially. it seemed good, but when i got some extra money i decided to try what everyone else recommended. The size of my groups not only shrunk but also got more consistent. Using these I found the cheap ones were usually off by .001 often more. Im sure these will make up the cost difference over time.

This is what you buy if you need to know the readings will be correct 100% of the time. Great tool.

Made in Japan, you know wont go wrong; it does cost a lot more than China copies, but all the controls are smooth and easy to use, no lag on anything. Although Im sure a $20 China made one can do the job too, but if you have a choice will you pick made in China? lol

Unsolicited feedback: With all of the fraudulent copy/knock-offs being sold online these days... I wanted to share with any potential customers that these Mitutoyo calipers are indeed genuine. These were purchased through the Amazon Mitutoyo Store and fulfilled by MSI Viking. Thank you!

Im a mechanical engineering student. Im using this for various projects and in the machine shop. Despite it costing more than competitors, I think it was worth it. The absolute feature is nice, not having to keep zeroing it every time you turn it on. I think the battery lasts longer in these than the competition; everybody elses calipers are always fritzing out because of low battery, but not mine. Oh, and these were authentic; I did a fair bit of research on how to differentiate from knock-offs. I made sure to buy from Amazon as the seller. I feel like these are the last calipers Ill ever have to buy -- a lifetime tool.

Its a delicate lab instrument and not a wrench that you just throw on the bench while measuring bullets or whatever. I received mine with a battery that is only a few months old. PROS - - Accuracy is high and consistent - I like the fact someone put their name on the QA/QC data sheet CONS - Mechanics of the jaws have a bit of slop, if you take a measurement inside the jaws measurement is consistent. If you take the same measurement towards the outer edge of the jaw the reading will be the same IF you do not drive the thumb wheel too hard. If you press the thumb wheel hard the measurement will be reduced a few thousands. I find its easier and more consistently accurate if you just close the jaws (press at the base rather than the tips) manually and do not use the thumb wheel.

This caliper works better than any I currently use.

Product functions as intended. Has been very solid for the few things Ive measured so far. I plan on putting this to use for better fitment in future projects!
