Digital Caliper, 6" Caliper Measuring Tool Extreme Accuracy Waterproof Electronic Vernier Caliper Industrial Stainless Steel Digital, Durable Measuring Tool with Large LCD Screen

I am so pleased with this tool! Very easy to use, comes with an extra battery, and pretty easy to figure out. The display is very easy to read, and you can choose imperial (inches) or metric (mm, cm) measurement systems. I love the large capacity, and that it also works with very small measurements, particularly screws.

This Adoric digital caliper is an inexpensive and usable tool. It's made of plastic, not metal, so get that out of your head. But for jobs that don't require a high degree of accuracy, it seems to work pretty well. I used it to measure a number of fasteners, tubes and openings and all came within the range I expected. Repeated measurements produced the same answer +/- 0.01 inch. The device easily zeroes and switches between metric and imperial measurement systems with the click of a button. The display is easily readable. It comes with an extra battery. For seven bucks, you can't have very high expectations, but this caliper does simple jobs pretty well. I would recommend it.

This digital caliper is great, and I use it all the time when I work on guitars (for checking fret height, nut spacing, etc.). The large, clear display is easy to read, and for general instrument work, the accuracy is more than enough. However, the one big issue with this caliper is that the battery does not last long at all. It seems to drain even when off. I’ve learned the hard way to always have spare CR2032 batteries on my bench, or you'll be halfway through a setup when it dies. It's a fantastic, affordable tool, but plan on budgeting for extra batteries. It's worth the hassle for the price.

As I have gotten into 3d printing, I am starting to make my own designs. Part of this is to be able to take accurate measurements of whatever you are trying to solve. This caliper is good enough to measure what I need, and I expect that it will work for the long term. The display is easy to read and switching between measurement systems is in the press of a button.

This digital caliper is a solid piece of gear. It feels well built and the stainless steel body is sturdy. I use it for my 3D printing projects to check tolerances and measurements. It works great and is worth the money.

Ease of use and accurate. Slides easy and quality product

Pros: • Has a large display (larger than most digital calipers) • Can display Fractions (along with mm & decimal inches options) • Units are displayed to the right of the number • Slides well, has a micro adjust wheel, and a lockdown pin on top • Uses commonly available CR2032 cell Cons: • Poor user interface (Zero and Power share a button) • Somewhat heavy • Too easy to accidentally zero out the caliper, resulting in wasted time I've had a plastic, Swiss made, General brand, dial analog caliper i've used to decades. It gets a lot of use, i treat it well, and it has held up well. I use it all the time to determine what size drill bit to use. I decided it was time to get a fractional digital caliper, to streamline my measurements. I have a non-fractional Harbor Freight digital caliper i rarely use, because it uses button cells (which i never seem to have on hand). I wanted a caliper which uses a CR2032 coin cell, and does fractions. I bought this caliper for use at a secondary location, and a more expensive Kynup (at nearly twice the price), to use as my primary. Ultimately, i decided to return this one because of its two-button user interface. The power button does double duty as a Zero button. Unfortunately, a short press on it zeros the device, whereas a long-press is required to power it off. If it were the other way around, i likely would have kept it. Since zeroing is something seldom needed/used by most people, and powering off will be needed by virtually everyone, a long-press should be required to zero. It may seem like a small thing, but it is far too easy to accidentally zero it when you don't want to (in part because of the position of the button on the device), which then requires closing the caliper, zeroing once again, then retaking your measurement. And it is incredibly annoying to have to do a long press simply to turn it off. This is especially problematic if you have other calipers with a proper user interface, as you have to remember that this is the one works differently. Engineers should be required to use devices they design. At the very least, the design team should consult actual users. (Think: Deming Quality Circles.) My Kynup has a dedicated Zero button (placed at the top, where it's unlikely to be hit accidentally), and the power button powers it off immediately. Proper design; what a joy! And because of its power button placement, i've never turned it off accidentally, but should i, it's a simple matter to turn it back on, and be immediately back in business. Definitely a keeper. Also, i like its display better. The fractions are bolder, and its use of smaller numerals for less significant digits actually improves readability over this caliper. However, unlike this unit, the units are displayed on the left side of the numbers; a design flaw, but minor enough i can live with it. Bottom line: This caliper has some nice features and will get the job done. If it's your only caliper, and you don't use it very often, it may be adequate for your needs. However the Kynup is much more of a joy to use, so was worth twice the price to me. Sometimes the little things really make or break a product. I still want a second, inexpensive caliper, so have the graphite-composite WEN 10761 on order to replace this caliper. It has a dedicated zero button, so am hoping it powers off immediately when the power button is pressed, like the Kynup. And being plastic, i'm hoping the weight will be more to my liking (i.e. similar to my plastic analog caliper). I expect its display isn't as large, but i can live with that. The photos below show this caliper, and the Kynup below it, for comparison. The two weigh approximately the same, thus both are heavier than i like. The maroon tinge on the display is an artifact of the camera and natural sunlight. Both display backgrounds, in real life, look like the Kynup's in these photos.

I was blown away by the quality for the value, physical measurements are not accurate but the digital ones are very accurate and almost never have any errors. Definitely would buy if you’re looking for something cheap that gets the job done well.
