Electronic Digital Caliper Inch/Metric Conversion 0-6 Inch/150 mm Stainless Steel Body Red/Black Extra Large LCD Screen Auto Off Featured Measuring Tool

The build quality is ever so slightly less than one would normally desire from a precision instrument such as calipers, but thus far that hasn’t affected their precision one bit; I use these almost daily for quick measurements on the fly, and after having checked their readings against those from “big-name” brands such as Mitutoyo or Fowler, they’ve only been off by about half a thousandth of an inch (the smallest readout these calipers have).My build quality concerns center around the housing for the electronics. The battery compartment in particular is rather poorly designed, as the battery door slides off to the right of the tool (looking down at it with the display right-side-up) and is positioned right where one would instinctively use their thumb to slide the tool open, but a quick habit adjustment to use the roller instead will solve that. The housing as a whole is made of plastic, and rather rough-looking plastic at that; even so, I admit to having dropped this tool or having dropped a piece of (small to medium sized) stock on it at least once without any damage to the housing nor any loss of accuracy.Its readout does change greatly depending on whether the tool is warm or not, so as it warms up from use it’s best to reset the zeroing, but fortunately this is extremely easy to do with the dedicated “Zero” button, which even some higher-grade digital calipers lack. These calipers are capable of switching between Imperial and metric measurements, again at the press of a dedicated button, and can be switched between absolute and incremental mode by holding the power button (the only dual-function button on the tool).I find myself wishing that GlowGeek also made a digital micrometer; then I wouldn’t have had to buy a Pittsburgh Tools one from Harbor Freight. That has served me well thus far as well, but I can’t help being apprehensive given Harbor Freight’s reputation for cheap tools that get the job done to a point and then fail miserably...

I got this because I thought the case was nice and it was metal. I had a plastic one that stopped working after a month, so wanted something better. I like the metal construction and the sharp edges. but that's about it. I use this very little, like maybe once a month. I noticed early on that it would shut off as i was using it for some reason. I would push the power button to get it back on which worked. but after using for an hour in one sitting, the button (on off) started to get smashed. It's not like i was jamming it down. it's just a little rubber nub. But it wouldn't contact for some reason so i had to keep pushing it. There is just something wrong with the way the buttons were made in my opinion. The on button is barely working now. In addition, the battery compartment doesn't seem to hold the battery very well. The connection seems to be loose or something, which might have been the reason it kept turning off.anyway, I just don't like the construction of the digital part of the caliper. I'm buying a new one from a different company and wanted folks to see what I thought about this one.

Pretty nice. I had to buy a set of replacement calipers for marking cuts for guitar frets which measure out to the thousandths. My previous set (another brand) had some major accuracy issues.For the price these were at I thought I'd give them a shot and they're pretty nice.They don't feel cheap, measure accurately without having to consistently zero out (although you probably should, I did it as a test of the accuracy). The depth gauge is a nice touch, I was measuring the depth of the frets I had cut just for giggles and found out how wildly inaccurate I was even with a saw stop. Guess I should use a table saw jig to cut frets, but that's another story.Works well, but the on/off button is weird. It turns the device neither on or off. I have to use the thumb wheel and it'll flip on, but it automatically shuts off after a few minutes so that works.

this is a handy little tool that seems at best be an Ok product for measuring. I bought it to measure gemstones, and the trick with that is to keep small gemstones level or the reading will be off. I measured a stone that I purchased as a 6.17mm, my jeweler said was 6.18 and this read as 6.16. Not bad but probably not good for any critical work. Feels kind of hefty, comes with a nice case and extra battery.

The Caliper is alright. Does need to be zeroed every time you go to measure. Not just every time you turn it on sometimes it is between measurements as well. The issue I had was when it arrived the battery was already dead and the"bonus battery was already old and leaking. I had to go buy replacements before I even got to use it. That just shows me a lack of care for their product. It's really frustrating.

I build a lot of things. And modify computer cases. I have calipers. But when I saw these on sale I had to have them. Digital readout!! Yes! I've only tested them once but they seem to work great. I'm going to take pics and do a "field test" soon so I can show them in action.Best feature is hold button so you can measure, hold the measurement and then bring them up to your eyes to see the numbers. I hate loosing my measurement because I move my calipers. I need glasses and have none. So these digital ones are going to rock!

Bad stuff:1) Sticky/jumpy slider. Not smooth at all. I can't stop on the number that I want.2) An air gap was visible between the inner blades when viewed from the end3) loses zero frequently. This is extremely annoying to take measurements then slide it closed and see it's not zero any more4) measurement from inner vs outer tips is not matching. Off by way too much5) The inner blades aren't at zero position when the outer blades close. An overlap is clearly visible on the inner bladesYou'd be better off with a ruler than to use this low quality tool. Even the $10 HF caliper is much better than this one!Maybe I just got a bad one.
