Digital Caliper 12 Inch,HARDELL Caliper Measuring Tool with Large LCD Screen,Electronic Digital Vernier Caliper Auto-Off Feature,Inch/MM/Fraction,Digital Ruler for 3D Printing/Jewelers/Woodworkers

I’m really impressed with this caliper. It feels very well made with durable materials not flimsy at all. It measures in mm, inches, and fractions, which is super useful depending on the project. The large digital display is easy to read, and it responds quickly and accurately. The zero button lets you reset at any position, which is great for relative measurements. Functionality-wise, it covers everything I need: inside, outside, depth, and step measurements — all smooth and precise. It came with two LR44 batteries, a sturdy hard case, and even a bonus stainless steel ruler marked in both cm and inches a really nice touch. I use it mainly for Fusion 360 design work, and the measurements have been spot-on with my 3D prints. I paid $30 USD, and they even gave me a discount coupon, which made it a real bargain for such a good-quality tool. If you're into 3D printing or any kind of precision work, this caliper is a great deal accurate, well-built, and affordable!

What a great value! I have been an automotive technician for over 20 years and this digital caliper is hands down better then any caliper that I could purchase on one of the tool trucks. The functionality obviously works the same but as you slide it to make measurements, it moves very smoothly. I compared it to two other calipers at my shop that are from the tool trucks and the measurements are identical. It is fairly lightweight and the display is well lit. It came with a battery installed and an extra as well. I was surprised to find that it also came with a precision screw driver for battery replacement and an 8” stainless steel ruler. This is a great tool. I will definitely be ordering a 4” & 6” digital caliper from Hardell to add to my tool collection at home.

I couldn’t be more pleased with this HARDELL 8-inch digital caliper—especially given how critical precise measurements are in my laser-engraving work. First impressions? It’s solidly built and pleasantly weighty, giving it that dependable, professional feel—yet not so heavy that it slows you down. You can handle it easily and quickly, sliding it into position without fumbling or fatigue. The accuracy is exceptional—exactly what I need when aligning materials for engraving (laser engraving goes by millimeters so it has to be dead-on). The clear and stable readouts mean I trust every fractional or millimeter measurement when lining up artwork or verifying depth and thickness. It’s reliable enough that I’ve recommended it to fellow makers and friends already—and everyone is equally impressed. What You’ll Love: Built like a tank, but easy to handle—just the right heft. Rock-solid measurement precision—no guesswork in positioning or alignment. Perfect for laser engraving—I use it daily to ensure every cut or etch on my laser engraver is spot-on. Highly recommended—I’ve already talked about this caliper to others and they ordered as well. They own other brands as well and were a bit surprised. If you're into precision crafting, 3D printing, machining, or any work where accuracy matters—especially laser engraving—this caliper is a no-brainer.

Very nice, well built caliper. Feels solid and operates very smoothly with readings in your choice of mm, decimal inches or fractional, making it very useful for machine work as well as woodworking or any application in which a fractional result is preferred. Uses readily available button batteries and includes two, along with a small screwdriver for changing them. An adequate plastic storage case is also provided. My senior brain wishes it had fractional rounding capability, to sixteenths, eighths etc.

I lost my calipers during our last move and while looking for a new one I saw that this one double the size of my old one new I needed it (I’m regularly wished my old one was just a little longer) so I love that I can now get precise measurements for bigger projects. Measurements are accurate and I really like that it automatically turns on when you start to adjust the tool and automatically turns off after inactivity. It’s really easy to use. Has all the functions that I would ever need and records accurate measurements for use in 3d design. Can’t speak to battery life - but it does come with extra button batteries inside the nice storage case. Also came with a metal ruler as a bonus that I was not expecting. In my opinion, is an easy 5 stars and a great value

Great caliper, great price. Works as it should. Turns on automatically by sliding, I'm really a fan of that instead of having to push a power button for every use.
