Fabricated from lightweight aluminum, it offers the best of both worlds - sturdiness without heft. The caliper/ruler combo boasts the ability to measure both internally and externally, accommodating various measuring needs. With its dual measurement system, it efficiently provides readings in both SAE (inches) and Metric (millimeters), with a capacity extending up to 24" or 610mm. Notably, its inside measurement commences at a minimum of 10mm (1cm), offering flexibility across a range of tasks. The addition of a locking mechanism ensures that measurements are held securely, eliminating the need for repetitive adjustments. Furthermore, its ergonomic design includes a handy hanging hole, facilitating easy storage, while its extended length makes it suitable for more extensive projects

Well made. Not for super precision, but certainly good enough for woodworking and 3d printing purposes.

It’s my new measuring tool for fitting clothes on a body. It’s long enough to measure from shoulder point to shoulder point and the exact width of the neck at different spots.

Exactly as I wanted. Some reviews say, "...innacurate out of the box..." If you don't know how to use the set screws on the head piece, do us a favor and just be quiet. This is the easiest way to check diagonals for squareness. It is perfect for transferring dimensions. Quick and easy to use. It could use a short instruction sheet to stave off the review trolls...

This tool is made of sturdy aluminum. Its Vernier measure is simple to use and as good as a dial. To prevent its becoming scratched, I made a card-board sleeve in which to store it.

well this is not the most sophisticated or pro tool I had. It lacks from some features common on smaller sized calipers (central needle for depth measures) but it is ok for my needs, is light and cheap.

... This worked out as well as I had hoped. Allowed me to get accurate measurements in areas it would be difficult to use a tape measure, or where standard calipers were simply too short. Anyone who has ever tried to cobble together an accurate measurement of an open space with two rulers or, worse yet, a ruler and some other pre-measured object, will recognize how handy this tool is.... A tape measure will do for some people, but for some purposes, the tape enters fudge factors and uncertainties that will have you designing something that won't fit properly.... Only drawback... I can't figure out how I'm supposed to take advantage of the 1/128" or .05mm graduations. I am assuming that is my own lack of familiarity with tools such as these, but some simple instructions would have been helpful. I assume the manufacturer expects customers buying a product as specific as this to know how to use it.... UPDATE: While showing this to a machinist, he pointed out the simplicity of the graduations. I don't have it in front of me, or a decent-sized picture, but when between two normal hash marks, which ever graduation lines up with a hash mark, that's the number of 128ths of an inch that get added to the measurement for fine resolution.... VERY handy tool, but watch what you use to clean it. Hash marks are not engraved, and certain solvents could remove them, and if you lose writing, you lose usefulness.
