The calipers I received appear to have a mistake. Instead of having only 25 increments on the moving jaw. I have 50, making this almost Impossible to read as your eyes need to focus very hard and you have to count the line instead of just being able to look at the lines and understanding what it says. Im not sure how this made it through but I’d imagine a whole batch is made like this so if advised staying away from these for a while.

I ordered this item because I needed to measure the width of a o-ring groove inside a small bore hole., A six inch vernier caliper would not fit inside the bore. This 4 inch caliper worked very well. The quality of the vernier is as good as the very well known manufactures of these measuring devices. Very pleased with the purchase of this item. (please note that I did not check the accuracy of this device)

Good calipers but had lots of unbroken sharp edges that needed cleaning up. Used emery paper to work them over. If you don't have good close eyesight might think twice about these.

Good, easy to read being small. Handy size fits into pocket without trouble. Glad for no hard plastic case! - wish it had metric also
