Electronic Digital Calipers, inch and Millimeter Conversion,LCD Screen displays 0-6" Caliper Measuring Tool, Automatic Shutdown, Suitable for DIY/Jewelry Measurement (New150mm Black Plastic)

I saw this tool when looking at watches on line that everyone seemed to be using to show the watch face measurement. I assumed it was some expensive tool for watch collectors. Looked it up on Amazon and it was only about $8. I am not a collector but have a few watches and like to buy certain sizes. Bought this and it works great, very simple to use, seems well made, came with batteries and a regular old tape measure so you can measure your wrist as well. So far very impressed, worked exactly as I expected it to right out of the box. Also has a nice little plastic case for storage.

This works beautiful. It's heavy duty, comes with a protective case and multiple batteries. The read is accurate and easy to complete. Definitely recommend

These digital calipers are very user-friendly — the numbers on the LCD are large and easy to read, even in low light. I appreciate the inch/mm conversion and automatic shutdown feature. That said, I’d feel better about long-term battery life if there was a small solar panel option. Also, since I keep mine in the bathroom (for quick jewelry measurements), I’m unsure if the humidity might cause future issues — time will tell. Overall, solid tool for the price!

Free books it's a good little measuring tool handy you break it by another and works well

Every time I need a set of calipers, I don;t have any. I always mean to buy a set, but never do. Today I NEEDED calipers and thought: TODAY IS THE DAY. Sometimes I need to measure bolts or the diameter of stuff. I ordered these yesterday and received them today. I needed to measure the size of the inner pice of my hose bib's vacuum valve. the piece was cracked and it was leaking. The inner diameter of the part differs from replacement part to replacement part. These helped to determine exactly the size I needed. They were accurate in that they measured the piece/part exactly as the measurements are stated in the description of the part I ordered. So I know they are accurate. They are very easy to use. The slide mechanism is very smooth. The LCD display has large, clear numbers. Changing from mm to inches takes the push of a button. There's a zero button, as well. I have never used calipers and I was able to figure them out almost immediately. They have multiple ways to measure: inside and outside diameter. They come with a case AND 3 batteries, -one already installed. For $8 you can't beat this tool. Everyone needs one!

Fantastic buy. Larger than I expected and perfect for my application. I restore fine art frames and get precise dimensions from this caliper.

Works as expected. So far it is accurate. Plus comes with 2 extra batteries. Packaged well. A bit light but good for the DIYer.

This is good to do piercings it's easy to measure and it's good quality for the price and easy to use and it's not that heavy.

No se cuanto vaya a durar pero por el precio esta perfecto para el uso que le dare, venia con 3 baterías extras - YaTeHabiaDicho | TTV

does the work. its a little clumsy, but then its also priced accordingly. Good for occasional use.

I had very low expectations for a pair of plastic calipers. Being plastic I wouldn't recommend them for machining but they could be useful at the desk to measure parts that you are trying to model in CAD. The repeatability is excellent. Spot on every time for 20 cycles in a row. I bought them to make a tail stock "DRO" and I thought plastic jaws would be easier to cut off then hardened stainless but now I think I might get another pair or two for measuring for 3D printing where super high accuracy is not required. Came with a battery preinstalled (with a plastic pull tab) and two spares in what has to be the most odd shaped case I've every seen. Overall, for low precession work like 3D printing, I would 100% recommend.

Great value; comes with 2 backup batteries in addition to the battery that already comes in it, a measuring tape, a nice plastic case, and functions exactly as advertised. Accurate to 1 decimal in millimeters and 2 decimals in inches. Isn’t as smooth and precise as an expensive set and is adjusted by pushing the head across the ruler rather than a rotating device, but that’s to be expected for a basic set.

Does a reasonable job of a vernier calliper. Although a little cheap build. The product is made entirely of plastic and I would have preferred a stainless steel one. But otherwise does a decent job. The digital display is good and displays out the measurement accurately.
