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

Seems to measure accurately enough. Compared to to a few tape measures/straight edges as well as a smaller caliper. It is accurate within the specified tolerance and is affordable so no complaints in that department as of now, will update if some emerge. For feel, it isn't the smoothest ever and the balance could be better. The small adjustment wheel is rather loose but does function properly. The knob to tighten seems to do it's job as well. The build quality seems to be a "Get what you pay for" type of thing, meaning decent for a decent price. For usability, it functions like you would expect calipers to function. My only grip would be that I wish it did not have an auto-on when the calipers are being opened. I would prefer to have it either default to making me turn it on or at least a mode switch to make it so it only turns on manually. Overall, very minor gripe and it does well for the price.

I got the 12in caliper, and this thing is much bigger than the 6in or 8in. While reading that, i know that you're probably like duhhh. But no, it's literally a scaled up version of the 6in one. You can tell that someone created the 6in caliper, then in the software, they just 200%'d the 6in one and called it a day. I figured the 12in caliper would be the same size, just longer, but it's literally 2x as big in every aspect, the head is 2x as big, the screen, etc.. QUALITY: So the quality seems top tier. It feels really tough. This thing is going to last a while, for sure. Slippage / Accuracy: So I've noticed that if you move the caliper quickly, it will have slippage, way more than the plastic 6in one I have. I could zoom the plastic one back and forth and it would never lose accuracy. But this one you can not. You HAVE to use the wheel or it will throw off the measurement. Weight: It's heavy af, way heavier than it looks, which is probably why it feels sturdy and feels like it's going to last forever. Overall, it's 8.5/10. If it didn't have slippage, it would be perfect. But there's no reason why you can't just always use the wheel. When I say it has slippage, it's not bad or anything.. it only happens when you zoom it back and forth a few times. I could never get my plastic one to slip, whatsoever, no matter how fast you went. This one, not so much. But again, as long as your using it at normal speed, it's perfect.

Product arrive on time, however the battery installed was already not functioning. After inserting the secondary battery the digital caliper functioned as designed. It appears to be of quality build, I plan on using it with my 3D printing hobby. Comes in a nice case and has a go of weight to it. The price was more than reasonable for a first time user of a digital caliper.

Updated 02/20/26: I took the whole thing apart, cleaned it. The issue persisted. I ordered a new battery. Instantly works just fine again. I noticed that in the case there's even a slot to hold the battery so you can take it out when not in use. Updating to 5 stars. Original: Failed after 1 year of gentle use. The display will no longer turn on/off, zeroing and changing measurement type has no effect. I used it maybe 6 times, it never left its carrying case otherwise.

The caliper works very well and is accurate every time. It holds its shape and does not flex when fully extended at 12inch. The scroll wheel motion is very smooth to adjust minimal amounts. It also had a auto turnoff feature after not using for a while and automatically comes on as well. Plus it holds its calibration and position from the previous use, I've used it to create models for my CNC and 3d printers and have had no true issues with measurements with the caliper. I highly recommend it, as it's definitely one of the cheaper calipers out there with such long length. I don't see this breaking anytime soon.

I cant imagine unless your machining sophistated parts that those high dollar calipers are worth the money (I am sure there are other uses for high dollar ones as well). This is GREAT to have in a few different sizes so you can keep one in your tool box, one in the job box, and a smaller one in the door pocket or back seat pocket. This thing gets used more than I expected. How can this be so cheap? So many times before I wished I had one handy. How big is that fence post? Whats the opening of that pipe? How wide is that trim? Sure, tape measures are everywhere but this is just too easy (as are all calipers, so I am not just pumping Neiko in general). I am ordering a smaller one now. The case is much nicer than I expected. Its not flimsy plastic. Its also not extra heavy duty so dont try running over it in the truck but you can sure have in a tool box and not worry. If it was high dollar of course I would be a bit more careful. Thats the beauty of not so expensive items, you dont have to baby it. REAL nice form fitting foam inside that IS high quality. This even came with a spare battery and a place to store it as well as a place to store yet another battery. I am truly impressed on the value of this puppy. Its MUCH better quality than I expected. VERY nice. This amazon system should score 1-10 or 1-100. If it did, I would give it about a 92. Why? The case sometimes is a bit hard to open but that also keeps it from opening unexpectedly I guess. And I would like to see the caseing around the actual digital readout to be metal but it IS a high quality plastic. I really cant find anything cheap about this product. So stop looking and kicking tires and just buy the thing. Might as well order a small one while your at it coz after you buy this one you will end up getting another one and that will just cost you more in frieght. See the buy button? Click on it.

I've used this thing a lot for 3d printing and it's always worked perfectly. The length of this is also super practical and I find myself using it in woodworking too due to how easy it is to use. Granted, I haven't tried many other calipers to compare against, but I don't see how this could function any better. Also! At one point it started acting a bit buggy and I thought it had died on me. I contacted customer support and they told me that the battery just didn't have sufficient power left. They then immediately sent me a replacement battery and checked up on me to see if it fixed it (which it did!)

I purchased this item in 2010, so 15 years of light use. Nice calipers, reasonably accurate, but like many inexpensive digital calipers this item eats 357 batteries like (insert the name of your favorite tiny snack food here); I mitigated the issue by removing the battery, and reinstalling as needed . . . quite the PITA. Manually hitting the on/off button is ineffective, the display powers off but there is still some sort of parasitic battery load. Last use I forgot to remove the battery, so now a week or so later, the battery is dead. I plan to gift these calipers to someone I don't like very much.

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.

Hello, I purchased this product back in 2021 and it is an amazing product. Good build quality. Works like a charm. In 2023, my team recently lost the batter cover and after reaching out to Neiko, they sent out a replacement cover free of charge within 1 hour of my email. Amazing customer service for a product that I purchased almost 3 years ago! Doesn't get better than this! Thank you

nice quality

Measures large dimensions with good accuracy. Easy to use

Buen producto a buen precio. Una inmejorable opción para el tamaño del calibrador; el detalle de contar con la batería extra hacen la diferencia. La entrega sin problemas, todo a tiempo y en buen estado.
