01407A

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 was worried this was going to be as bad as another digital caliper I had ordered because it looked nearly identical to it, but was pleasantly surprised when it worked like a charm. Not to mention, it felt significantly heavier and nicer with the stainless steel body. So far it has been great and within +- 0.01mm.

A quality digital caliper. Accurate and convenient to use. Seems solid.

This pair of calipers seem to really well built and accurate. i have only needed them for a handful of things so far but they have been accurate thus far. i love that the digital screen makes it very easy to read. also really nice that it come with a plastic case to keep it safe.

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.

I ***HOPE*** that I got a lemon, and it's a titanic lemon at that. First it arrived on and running in the box. The values on the dial were changing continually to random numbers. The reset button had no effect (as I later found out) also dd the in/mm button. So after learning that the reset button was useless, I removed the battery and gave the unit a minute or two "to relax" in case there was a small charge left in its circuits. Then (after 10 minutes actually) I replaced the battery, and was surprise that the unit turned on immediately (although I had very carefully avoided touching the on/off switch). Surprisingly the same random displays started up immediately but this time after using the reset (clear?) button several times and then holding it down for about 30 seconds, the weird behavior stopped and left me with a set of random digits that meant nothing that I could imagine. So I (a) removed the battery, (b) cleaned the unit thoroughly removing any oil/grease/water/dust/pollen/whatever from the unit (just in case) and put a second new battery in it and turned it on. It initially showed a random value but the reset button seemed to work (that was wrong but i hadn't figured that out yet). When it turned on I made sue (using the thumb wheel) that the caliper was pushed back in to the "0" position and hit the reset button. It then showed -0.03" (I didn't write down the last digit ... sorry), but after 5 (yes FIVE) resets it finally showed 0. So I tried to use it. I have a set of calibrated 1-2-3 set-up blocks (1"x2"x3" certified as accurate to withing +/- 0.0005") and none of the measurements was anywhere near the values the caliper should have shown. Specifically the 3" side showed as being first 5.9... inches then suddenly 1.23.. inches then some other random number. The other two sides were measured with equal inaccuracy. So why go on? Because I'm a retired physicist and I'm used to dealing with things that "don't behave in a rational way." [ever hear about quantum mechanics? Yes, it's that illogical.] To make a long story short the reading were random and they changed of their own volition while the caliper was sitting on a desk and nobody was touching it. I tried it with three different batteries, and the results were NOT all the same - no instead they were all equally, randomly incorrect. I sincerely expect that this is just a bad unit. But my last calipers were a really cheap set from Igaging (made of plastic at that) BUT those are still working just fine and with completely accurate, repeatable results (I still have an older manual set that may have come over on the Mayflower but is still highly accurate - I just prefer digital for ease of reading. But it's great for checking accuracy - and it and the plastic Igaging set always agree to with the limit of my eyesight (sorry - a magnifying glass and a bright light helps). So i will be returning this unit and am going to buy another set. But you can safely bet you life savings that i will not be buying another set from NEIKO Because this unit was so unreliable and inaccurate, I cannot recommend it to anyone who doesn't simply want a strangely-shaped paper weight. From my experience it is definitely not a good purchase.

Honestly for the low price of $25 I didn't expect much out of these calipers. I figured they would be cheaply made with way to much play in the jaws or slide key... But they aren't! I couldn't believe how well built it was. There was absolutely no play in the slide even at full extension! I've had mitutoyos that had more slop. The measurements are dead on, it claims accuracy at +/- .001 and they weren't kidding. I used a .010 gage block as a reference measurement and the neiko calipers measured it at .0100 I mean if that's not dead on I don't know what is. The fractional readings are also an absolute bonus! finally no more wasting time having to convert a decimal value to a fractional number. Anyway with all those positives I can still point out a few negatives that should be mentioned... The slide itself has no play, with that being said it's so tight in the slot that you can feel it kind of dragging or just not sliding smoothly cause of the friction build up... No problem! Oil the slide with a few drops of air oil, clock oil, or a light gear oil. Do that once a week or monthly pending how often you use them and that slide moves like butter. The next negative is the buttons, they don't always register when you depress them... Again it's not really that big of a deal but if it doesn't work 100% everytime then regardless it's still a problem. The last and final issue is probably the biggest and this is going to really depend on the application your using these for... But the jaw tips are fairly thick, significantly thicker than the jaws on a set of mitutoyo this does limit your ability to get those jaws into super tight spaces. For instance if you need to determine the shank size on a small bolt say like a 1/4 - 20 the neiko calipers jaw tips will not fit between those threads. So in hindsight, that really does limit effectiveness. If you need that kind of flexibility and absolute precision obviously mitutoyo is the way to go... If you don't save yourself about $175 and buy a set of Neiko digital calipers! Last and final opinion... I was reading through several of the previous comments and alot of people seemed to be complaining about screen issues or zeroing issues.... Did yall ever happen to think "oh well maybe the battery is dead or dying"??? These calipers come with a battery already installed, and who knows how long they were sitting on a shelf before being shipped out. Batteries don't last forever folks! My best advice is when you get the calipers delivered first thing you need to do is just simply change out the battery with a new one. They take LR44 and will also accept SR44 batteries. So buy a set of neiko calipers today, go get you a pack of LR44 batteries tomorrow, stare out the window, and wait for that Amazon truck to roll on up!

Works well
