NEIKO 01407A Electronic Digital Caliper Measuring Tool, 0 - 6 Inches Stainless Steel Construction with Large LCD Screen Quick Change Button for Inch Fraction Millimeter Conversions, Digital Caliper Measuring Tool

Fit and finish are pretty good, it didn't come full of grinding grit like the uber cheap calipers tend to be. You might need to tighten up the gib screws before use, mine were a little loose. Be careful though, they are easy to strip.The newer ones with the screw-on battery cover seem to have improved battery life over the old ones. I measured the quiescent current to be 14.4 µA (15.7 µA with it on). Assuming a somewhat conservative 120mAh of battery, that'd result in just short of a year of standby battery life.

I bought this because I kept reading so many different thickness measurements for materials and I wanted to figure out if some of the materials that I had already purchased would work in particular machines. For instance, the Silhouette Portrait will only cut materials up to 0.8 mm so when I was looking at chipboard and whether or not it would work in that particular machine, people would have so many different measurements that I just couldn't figure out if a product was worth purchasing or not. I have a bunch of different materials that I have purchased over the past and did not end up working for me, so I got this to measure the thickness of those particular things.First, let me address the quality. It seems to be of pretty good quality. It is sturdy and moves easily (doesn't get stuck when trying to open or close). The digital readout is big and is extremely easy to use. There is a red button under the digital readout that you can push to turn it on or off, but it also automatically turns on when you slide it open. You can set the zero on it to any point which might come in handy for people that want to measure from a larger point (like comparing the exact same items to see if there is a difference or something).The case is OK... It is sturdy and it doesn't feel like it will break easily. It is plastic, but not a thin plastic. My only complaint about the case is that it looks like a tool case! haha. I will have to add some color to it and make it look less like something my husband might want to steal. It is also a little difficult to open at times for me but perhaps that's because I'm used to the easy girly tools. ;)There was a battery already installed and an extra one in the case. It uses a LR44 button cell which is VERY common in kids toys so I have a huge backup of batteries for this thing. Those batteries tend to be rather expensive if purchased from a local store for some reason. They are often times seen in watches and that's usually the department we would find them in when we used to shop for them. I actually found them cheaper on Amazon and ordered 100 batteries for less than the price of 2 at the local store. So, maintaining the battery for this should not cost a lot of money.I have one major complaint with the design of this and it has to do with the battery compartment. I realize that there is a spot to put your thumb to slide the blades open for use, but I tend to put my thumb directly onto the top which is where the battery compartment is. So, I almost always slide the cover off. I don't know why I do this and it probably has to do with the fact that I use other items that require that type of maneuvering, but it IS something that I do and other people might as well. Although it doesn't technically hurt anything to do that, the battery can (and will) pop right out of there if you don't catch yourself when you are doing it. For the most part I don't have problems with that happening, but I'm confident it will at some point. If there is any chance of this getting redesigned in the future, I would make it slide a different way so there is very little chance of accidentally sliding that cover off at all. It's a little irritating but not so much that I regret the purchase... because I really like this caliper!As for the price, I think it is well worth the money that I paid for it. I'll be using it like crazy to give some accurate measurements of items that I have seen incorrect information on and it will save me time and money on products that I try to create with my different machines. All I have to do is keep it away from my husband now!

It appears to work well. Measured a 1-2-3 block several times and measurements were dead on every time. The only issue I have with it is that it was supposed to be to come with 2 batteries. 1 in the unit and a spare. It did not come with a spare battery and the one that was I. The unit was dead.

I'm used to using my Mitutoyo 505-626 analog caliper. I figured "It's not the seventies any more, analog calipers went the way of bell bottoms" & decided to "upgrade" to digital. I read a bunch of reviews and watched a bunch of demo videos. I didn't want to spend a fortune, I already have a caliper, and new Mitutoyos are like $200 for a digital one. Analog Mitutoyos are $80! So, I bit the electron & bought a digital iGaging IP54. By the looks of it, I suspect other companies make this same caliper.The good: cheap; digital display makes it easy to read (although it FEELS weird, like going from an analog speedometer to a digital one, your brain has to interpret the numbers, it can't just "feel" the measurement); looks cool; comes with a snazzy, well-padded, although all-plastic, case; pretty accurate (see below); new.The bad: not as smooth as the Mitutoyo (I never considered the Mitutoyo "smooth," but it's WAY smoother than the iGaging); the box that houses the electronics is too large (it isn't svelte like the analog, its boxy in a big-boxy way); quality of materials and craftsmanship, including case, is a notch lower.Why it comes with a spare battery I don't know. I hope it doesn't eat batteries like I do Gummy-bears or we're in for a short honeymoon.I measured a stock piece of cylindrical material used to test and calibrate measuring tools. I guess it's 1/8". Both the analog Mitutoyo and the digital iGaging measured identically: .1265. Now, I KNOW 1/8"=.125, but maybe that is operator error, or maybe the temperature of the materials, but at least both machines were the same. I also tried measuring using different parts of the iGaging calipers' jaws and the reading was identical the entire length. I'm not sure how much more you could ask for, other than the buttery smoothness of the Mitutoyo, but for what it costs, I don't think this tool can be beat.

I rarely need a digital caliper this long, but when I do this works well. Accurate, compared to some high end scales. Well made, operates smoothly, good battery life,
