NEIKO 01409A 12” Electronic Digital Caliper | Extra Large Display | 0-12 Inches | Inch/Fractions/Millimeter Conversion | Polished Stainless Steel

Extremely helpful with sizing gemstones and also doing some gunsmithing, making sure everything is in spec. So far it returns to zero (0.00mm) accuracy even when sliding recklessly. Tool comes out of the box very clean, stainless steel is good quality and not warped, plastic measuring face is average. I wiped it all down and applied light gun oil down the channel. Feels solid and as long as it's treated nicely as you would a Mitutoyo it should last about as long.

does what it should. very accurate for CAD modeling for 3D printing. I could not live without this little tool. Like the metal body and the large display. I will say, however, that the power and reset buttons are very sensitive and set too near the thumb screw. This will cause you to inadvertently recalibrate or turn off the device when using the thumb screw for minor adjustments.

The Neiko Electronic Digital caliper is accurate and easy to use for measuring any thing that requires precise accuracy. The digital display is clear and makes it simple to read measurements without guessing. It feels well made for the price and has held up great with regular light use. Switching between measurement units is quick and convenient. However, the battery often loses connection, causing the display to flicker or reset unexpectedly. Reseating the battery usually fixes the issue, but it can be annoying when you’re in the middle of a project. Overall, it’s a good value and performs well most of the time, but the battery connection problem keeps it from earning a full five stars.

Real nice caliper for the price. I tested on some known measurements, and it's accurate.

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.

So far so good. this thing accurately measures even wires down to .007 inches. came in handy for a bunch of projects. Good to have on hand, so fast standing up to the test of time.

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.

Very nicely made Caliper. The added bonus of it showing fractions has already been a handy feature I have used a few times. The bottom line is this, if it became non-functional through my own carelessness, I would buy another no-question HOWEVER..... after two months of use I am finding the two font sized readout very annoying, Otherwise it has worked well but I do not understand why it was decided to make the second, third and fourth numbers after the decimal half the size . If someone only needs it for coarse measurement then having the first two numbers predominate makes sense but I personally find the two sized readout less than Ideal and I am looking at other calipers that show the readout all in full size

Buen calibrador, mide en milímetros, milésimas de pulgada y fracciones de pulgada. Comparé su precisión contra un Mitutoyo análogo y es bastante preciso, por el precio está muy bien. Lo que no me gustó fue que la pila venía ya dentro del vernier y pues ya estaba descargada cuando lo encendí por primera vez, me marcaba error. Solo tuve que cambiar la pila y problema resuelto. Recomendable producto.

La mejor opción barata, este ya es de por sí sensible entonces una opción más barata seguro se rompe con verlo. Con cuidado y precaución de seguro dura otros 10 años más y por ahora lleva 6 meses funcionando perfectamente. Buen producto, sin quejas por el precio.

Received goods as described, shipping is per planned arrive date and a well packed shipment

The materiality is great, it looks and feels like a quality item however I have owned it for approximately 6 months and in that time I've used it perhaps a dozen times. It is stored indoors in a steel work bench inside of its hard carry case. Now the digital display is glitching and does not maintain a reading. Edit: turns out a battery replacement solved the issue
