Spurtar Vernier Caliper Measuring Tool 6" Stainless Steel, 0-6Inch/0-150mm Manual Non Digital Calipers, 0.001"/0.02mm High Precision Durable Micrometer

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.

The caliper is pretty good. There are some nicer aspects missing from it, but overall, it is okay enough for little hand-made projects.The good:Little to no play in the slide. It doesn't have any jiggle, and the measurement stays put.The lines are fine and accurate. I can do my little tinkering projects easily enough.The seller contacted me to warn me that other customers complained about the packaging and to watch out for damages when it arrived, but the box did a good job of protecting it. It was in great shape.The bad:The thumb roller isn't a roller! I laughed when I first unpacked this. It's just a stationary thumb grip. This makes the sliding action less comfortable and easy with one hand.The machining is pretty rough.Overall, if you want it for precision tool work, I would not recommend. But if you're working with wood or small household projects, it's great to have around.

When it's closed it reads zero, and when I put it up against a few gage blocks it read right. The price was right. What more can you ask for?

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.

Quality seems excellent. My HF digital caliper also claims 001" precision and also shows the next half-thousandth (.0005"). It matched this vernier caliper, nearly always to the half-thousandth. And two other inexpensive calipers matched this vernier caliper. The one I received seems to be built correctly in contrast to some other reviews.However - I thought I could read Vernier, I learned on pre-electronics land survey instruments long ago. But the graduations on the Inch scale are so close that I mis-interpreted the reading, about one-third of the time.And note you will need a magnifier - I use a jeweler's headband stereo magnifier - to see the reading.I would write down what I thought was the measurement. Then the digital caliper, about a third of the time, would show at least .010" larger. Back to this vernier caliper, I found a matching tic at that larger measurement that also was as perfect a match as what I had relied on.One workaround for this mis-reading is to look at the measurement on the coarse scale and estimate between the tics, for example 60% of the way to the next tic. Then go look for a perfect match on the fine scale. In the example of 60% that will be about +.014". (60% x .025" graduations).This thing is definitely Old School. No battery needed, which is why I bought it. But the need to use a magnifier to read it makes it less convenient than the modern digital one.I watched a YT video explaining a Starret (famous quality brand) vernier caliper and I see the Starret is easier to interpret. Its coarse graduations are .050" while this one has .025". And its fine scale is twice as long with larger graduations, so its easier to see where tics match. With good eyesight a magnifier wouldn't be needed.The ultra-small graduations are not only hard to read. Coarse graduations of .025" plus adding a number 0~25 from the fine scale to arrive at total measurement is more confusing than I expected and prone to error. The Starret, for inches, and the mm scale on this, are easier math to work in your head. If you don't understand this paragraph then a vernier caliper isn't for you!Overall - a quality tool but for purists. For general use go to HF and get their .001" digital caliper, and some spare batteries. Several reviews here rate that tool better than other inexpensive digital calipers.I gave up and returned this. Expand the photo at the head of this listing. (And you will need an excellent magnifier to see anything like that). Is that showing 0.670" +0.001? +021? +.022? I can't measure with thousandths precision because I can't distinguish which tick is best. I made too many errors compared to using the digital caliper which was unambiguous.
