Spurtar Vernier Caliper Measuring Tool 6", 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.

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.

It's definitely in the details and the photos etc. but I guess I'm just blind and didn't realize the inches were divided into 10ths (like 0.1, 0.2, 0.3, 0.4) as opposed to subsequent halves (like 1/2, 1/4, 1/8, 1/16). It's fine, just not what I'm used to. Math is math.Otherwise, very nice caliper given the price point.

I needed a pair of calipers to measure the accuracy of my 3d-prints and this has done the job really well. The included ruler for quick and dirty measurements or as a solid line tool has also been handy. Pretty good item for the cost.

OK, as I said, I'm not a technical engineer who has any real experience, or need, for a tool like this. So I'm just giving my opinion overall. I build R/C aircraft, and a set of calipers can come in handy many times when I'm trying to duplicate the sizes of something.I did some research on calipers, and from what I read and watched this is a fairly decent caliper. One point I learned was checking the zero point match, and they do on this set, and that there is no visible gap between the jaws when they are closed, and there weren't, so they appear to be accurate.The instructions tell you to lube the contact points with clock oil, and I used sewing machine oil (same thing I would guess) and I actually did it BEFORE I read the instructions (Hey, I'm a guy, all right?) because the calipers were a little "scratchy" feeling as I slid them back and forth, it was much better after being oiled.I tried measuring a set of feeler gauges to test the accuracy, and what I read on the calipers matched what was etched on the feeler, so the calipers seem to be as accurate as I would ever need.I also love the 6" ruler that came with it, I have several of that size, but they are hard to read (don't get old!) and this one is nicely marked and easy to read. The case it comes in is great to have to keep the calipers protected in my toolbox too. I'm satisfied with them.
