NEIKO01407A Electronic Digital Caliper Measuring Tool, 0 - 6 Inches Stainless Steel Construction with Large LCD Screen Quick Change Button for Inch Fraction Millimeter Conversions, Digital Caliper Measuring Tool

This review is for NEIKO 01407A Electronic Digital Caliper | 0-6 Inches | Stainless Steel Construction with Large LCD Screen | Quick Change Button for Inch/Fraction/Millimeter Conversions. Let me start of by saying that if you need a gauge that is highly accurate and highly precise, you are going to need to shell out some good coin for something like a Mitutoyos.I picked up this NEIKO caliper, because I wanted something that was quality and not expensive. This caliper has been excellent so far. It is stainless steel, which was a must. I want it to last, and I wanted something more precise/accurate than plastic. I also wanted something digital for ease of use. This gauge is extremely easy to use. You can scroll through millimeters, inches, and fractions of inches. The display is also easy to read. This also comes with a nice storage case, one battery installed, and a spare battery. The owner's manual fits inside the case, and there is room for a spare battery in the case. The only thing I can say remotely negative is that the installed battery arrived dead, but the spare battery was good. I've already used this multiple times around the house for various things, and I wish I had bought one of these sooner. It has been extremely helpful for multiple projects.

I'm used to using my Mitutoyo 505-626 analog caliper. I figured "It's not the seventies any more, analog calipers went the way of bell bottoms" & decided to "upgrade" to digital. I read a bunch of reviews and watched a bunch of demo videos. I didn't want to spend a fortune, I already have a caliper, and new Mitutoyos are like $200 for a digital one. Analog Mitutoyos are $80! So, I bit the electron & bought a digital iGaging IP54. By the looks of it, I suspect other companies make this same caliper.The good: cheap; digital display makes it easy to read (although it FEELS weird, like going from an analog speedometer to a digital one, your brain has to interpret the numbers, it can't just "feel" the measurement); looks cool; comes with a snazzy, well-padded, although all-plastic, case; pretty accurate (see below); new.The bad: not as smooth as the Mitutoyo (I never considered the Mitutoyo "smooth," but it's WAY smoother than the iGaging); the box that houses the electronics is too large (it isn't svelte like the analog, its boxy in a big-boxy way); quality of materials and craftsmanship, including case, is a notch lower.Why it comes with a spare battery I don't know. I hope it doesn't eat batteries like I do Gummy-bears or we're in for a short honeymoon.I measured a stock piece of cylindrical material used to test and calibrate measuring tools. I guess it's 1/8". Both the analog Mitutoyo and the digital iGaging measured identically: .1265. Now, I KNOW 1/8"=.125, but maybe that is operator error, or maybe the temperature of the materials, but at least both machines were the same. I also tried measuring using different parts of the iGaging calipers' jaws and the reading was identical the entire length. I'm not sure how much more you could ask for, other than the buttery smoothness of the Mitutoyo, but for what it costs, I don't think this tool can be beat.

It appears to work well. Measured a 1-2-3 block several times and measurements were dead on every time. The only issue I have with it is that it was supposed to be to come with 2 batteries. 1 in the unit and a spare. It did not come with a spare battery and the one that was I. The unit was dead.

Lets be clear:This is the NEIKO model 01401A, six inch, stainless steel, digital caliper with extra large LCD display.It comes with a sturdy plastic, utilitarian case, a mini screwdriver, the instructions and ONE battery (installed).Nowhere in the product description, instructions or on the box is there mention of a spare battery. HOWEVER, the product description says the battery is an LR44 where the box and instructions state the battery is a CR2032. I opened the battery compartment to verify and found the battery to be the CR2032..The caliper itself looks, feels and performs like a quality piece of equipment. All the buttons work smoothly as described and the thumb wheel IS a bit loose in operation but not at all annoying.There is a fraction/decimal equivalence chart on the back. Usefulness is doubtful especially as the print is VERY small.The instructions appear simple and straightforward. Keeping them handy with the tool would be a good idea as accessing the battery compartment to make a change IS NOT INTUITIVE nor are the instructions completely clear. Once the screws are removed (carefully, they were tight), the directed movement of the thumb wheel is minimal. THEN, the entire back lifts away enough to free the battery tray which can be removed with your finger nail. On reassembly, I put a small drop of silicon grease on the screw threads to ease any future removal.The typical home user, hobbyist, and do-it-yourselfer will likely find this exceeds your needs or expectations. I feel that I should have gotten one YEARS ago.Addendum: There is an undocumented USB-C located on the top edge of the tool. An email sent to Neiko concerning it's use / purpose has been acknowledged but not yet replied to.
