Measure depth of objects with depth gauge blade.
Measure the step height utilizing the back step of the caliper.
The Way to Read a Vernier Caliper in Metric & Inch Size
Tips
- Keep the surface clean, prevent liquid from getting into the slider and do not immerse it in any liquid.
- The surface of this manual caliper should be cleaned gently with medical alcohol.
- Use a small amount of micrometer lubricant to wipe the reference end surface and sliding parts.
- Store the caliper in a clean, constant temperature and humidity, avoid high temperature, high humidity, dusty and oily places. (Attached with storage case)

Most of the other reviewers complains about various issues with this caliper: accuracy, oily, possibility of rust, roughness of edges. All right complains, but they need to be put in perspective. If you are considering the purchase of a vernier caliper you know at least something about mechanics. How many parts made such a device? Building that many, with highest quality material, to the highest possible standard for accuracy (hence sharp) on one side of the part (the "internal") and for user friendly (hence smooth) on the other side (the "external") cannot be made cheap. All manufacturing procedures have tradeoffs. So for the price, this is an excellent product. Is it accurate enough? Yes, mine is accurate to the level of the vernier scale, however a tiny bit wobbly at that level, hence one less star in accuracy. Easier to read. Is it oily? Yes, but for most use that's minor problem. Is it rusty? No, but the manual says that if you clean the oil completely it might become so. Is it smooth? No, it's a bit sharp. If I had time to spare and would use it more often than I do, I'd try to smooth it with a file. But for occasional use it's totally usable. At this price, it totally deserves five stars. Granted, if you compare it with a similar one costing 10x its price, it would barely get two stars, perhaps it'd get even just one. But that would be an unfair comparison, like a race between an accomplished world champion and a random kid in middle school.

Bought this five years ago and really like it. Measures about .001 over and that's fine for the price. Looks like you might be able to calibrate the vernier scale but not worth the effort. The inch vernier is a little hard to read if you really need that last thousandth, but it works. Works just fine, reliable and no battery. For the price it's an excellent value and useful to have around. Very clean, simple and functional. The knurled thumb adjust is not a rotating fine adjust wheel, just solid bump.

Overall, this caliper seems well made and the stainless steel gives it a good weight. I don't have a good way to check accuracy, so others will need to cover that. As others have pointed out, the Vernier scale is hard to read (but might be ok for younger eyes). I will probably just keep a magnifying glass handy. This will be fine for woodworking, but I would recommend a dial caliper or digital caliper if you need better accuracy/precision, or if you are worried about being able to read the scale. Also, you need to be careful with the included ruler (if you don't just toss it). There are various scales shown, and the 1/10 markings on the one section are closer together than the 1/16 markings on another section.

Overall, these are great calipers! I tested against several rulers, a measuring tape, and other standards for accuracy. The calipers are always right on the spot for measuring and are very sturdy. I like that the calipers can be locked to keep your measurement. There is also a feature that allows you to measure depth of a depression using the sliding rod that comes from the bottom. This turned out to be a very handy feature!Overall, these are very accurate and seem to be really sturdy as well! It is worth it to mention that they also send a little ruler with the calipers that comes in handy elsewhere.I heavily suggest buying these if you need a standard and reliable pair of calipers. My experience with the digital calipers is that over a short period of time, the digital display messes up and they are basically unusable at that point. That is the main reason I got these. They are sturdy solid metal as well! Far better than any plastic pair.

Don't expect perfection for $17. Works adequately for my semi precision purposes. Slide action a little rough. Slider doesn't stay in place like my old Craftsman, the friction mechanism isn't so good. Vernier calipers are all a little hard to read, so that is to be expected. If you want easy, get a digital or dial caliper.

This is exactly what I needed. Working on bicycles, I need to order stainless steel bolts to replacement some of the more non-standard ones I find. As received, I verified the tool met their stated level of accuracy. Quality, solidly built tool, and I can verify the case received was in perfect working condition. Best of all, the battery never dies and the digital accuracy never changes and needs to be recalibrated. Yes, a millimeter is a small thing, and the numbers are small and may be hard to read if you have poor eyesight. If my eyesight deteriorated, I would still by this tool - and just take a pic of the scale with my phone and zoom in to read it.

Seem very good quality for such a decent price, they're deceptively heavy and seem accurate and sturdy.
