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.

Cheap. Works. Accurate. Has a case. Enuf said.

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

Works great and you can not beat the price

Works great - so many uses. Thanks for 2 extra batteries - love it! I use calipers for sale of my watches. Durable item. No issues. :)

This was a game changer for me. I don't know why I didn't buy one sooner. This has made my 3d printing so much easier. The quality is great. The design is perfect. The plastic and metal have held up and measures great.

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!

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

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.

Good quality and measurement

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.
