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

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!

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

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

They're as accurate as the expensive ones I misplaced. Good weight, slides easily without slipping. The out off is really nice because I, like most, forget to turn them off.

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.

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
