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

Was very skeptical especially with all the fakes. I bought through LLC Amazon, and after doing quite a bit of research I believe these to be real. There are 4 zeros before the decimal point when in inches, and 2 zeros before the decimal in mm, the finish is very nice, even the box is very sturdy. The battery is the correct SR-44 and comes in its own plastic packaging (in the caliper box), the zero button has to be held when you fit the battery, when doing this make sure you put squeeze them closed to ensure correct readings. I contacted Mitutoyo to ensure the certificate of inspection of genuine as the signature and stamps look to be printed on. They viewed photos of the documents and believed them to be authentic, I think Mutitoyo must be printing signatures now... I also saw a review of someone else which posted the photo of this card, and it had a different serial number to mine which is another indication the item is authentic. For the record my serial ends in 554 so chances are if we all have different serial numbers the item is authentic as they match the item and certificate. I hope this helps someone. Thanks.

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

I was a little leery to buy an expensive caliper with all the other less expensive ones but my neighbor had one and I liked the way it worked. This is easy to use and seems accurate to me. The thumb scroll is easy to use and can do small increments as well as moving faster for larger ones. You can lock it in on a measurement and then compare it to anther item. You can also take measurement, zero it out, take another one that’s thinner or wider and get a difference. I didn’t think that would be useful but I used it the first day. It’s sturdy and well built. Uses a common battery which is easy to change. Overall it’s been a great addition to the measurement line of my tools. I recommend it. Spend the extra money for accuracy and durability.

It’s been over a year since I purchased my calipers and they’ve held up greatly. Within half a thousandth accuracy repeatedly just making sure I’m straight and not canted is the difference and used micrometers to double check and usually within .0001” to .00005” and held up to the coolant droplets and shavings of metal that I constantly wipe off to measure.

I have been buying calipers for several years and never this satisfied. Of course all others most likely were chinesiums. Some, I purchased and was very happy for a few days, weeks, months. Battery died within 6 months. I thought that was the norm, so I purchased a dozen batteries to keep as needed. But lately Ive done some research and decided to spend some hard earned money into this caliper and I am very happy. I also purchased one at half price on ebay 2 days ago, but had to cancel the transaction before the seller could ship. I first asked the ebay seller if this was genuine and made in japan, to which he said yes and yes. However, after watching several youtube videos, doing some more research and contacting the company, I asked this seller to please cancel the transaction before shipping it, which he did and I got my refund last night. This morning at 7.45am, I received this new one from Amazon and I was super excited to open it and see if all what I heard and saw was true. This of course feels terrific as was noticed by others. But feeling is not the purpose of this caliper. It sure does not even flicker the numbers like my others did. The numbers on the screen are distinct, and repeatable. All features are on point. I measured several items, inclding paper thickness of various papers. All measurements repeat exact same. I then proceeded to do the ampere testing with my Fluke multimeter. Sure enough, the usage drops considerably when off, not like the others that use almost the same current whether on or off, thus explaining why their batteries die so soon. Bottom line, although I spent a lot more money than the other calipers on this one, am I satisfied? Yes. No regrets at all for the first time, on a caliper purchase.

A bit disappointed. I bought an iGaging caliper that works just as well and accurate (100 700 06) as the Mitutoyo. Im not complaining about the caliper but I am complaining about the protective case the Mitutoyo comes in. iGagings cases are much better and I am disappointed with the Mitutoyo case hinge, it looks like a razor knife cut right on the hinge and will break loose in short time. I called MSI viking the seller and they have no record of my purchase through Amazon, therefore they will not send me an undamaged case under warranty. I will be calling Amazon customer service and tell them that I am not happy and may request a return and credit. All I really want is a new case thats not damaged, at the price you pay for a Mitutoyo I would expect more than less and would appreciate service. I only decided to buy from Amazon and the MSI viking vendor since there are so many counterfeit Mitutoyos being sold online and that MSI Viking is a Mitutoyo distributor. I am updating my review. I got a response and MSI-Viking sent me a new storage box and replaced the defective one. Somehow the original order was not in their (MSI-Viking) data base due to my purchase through Amazon. Im happy and pleased. many times after the sale you get no response from the seller. I was vey hesitant about buying a Mitutoyo caliper since there are so many counterfeits sold as the real thing and some at even a higher price. I did contact Mitutoyo for a list of authorized distributors and I do urge that if you buy from Amazon or E-Bay to only buy from an authorized distributor such as MSI-Viking. MSI-Viking is an authorized distributor for Mitutoyo, Starrett, Browne and Sharpe, and Mahr Federal. I assure you they are the real McCoy. Hope this review helps you make your choice. I highly recommend that you contact them and save on the shipping with Amazon Prime.

The difference between Mitutoyo and the cheap knockoffs are readily apparent the 1st time you use them. These are smooth and accurate and the fit and finish are very nice. They are pricey but you are paying for precision.

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.

I bought my first Mitutoyo calliper 50 years ago and its still in good condition except the edges for inside measure gets little round. Now its much easier to read in mm and inches (not guessing), i like it (Ok its all depends how you care for the tools) . . .

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!
