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.

Highly accurate. Easy to read and easy to use. Great price

Great tool to have when you need to measure the diameter of something. Always wanted one but this gauge finally made me buy one due to the price and case. Works well when I’m trying to 3D print.

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

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

We use to measure shells and gems. Accurate and easy to use without the high cost. Happy with the quality.

Accurate easy to use caliper. Excellent price for the quality you get. Everything works as should.

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.
