UPDATE 3 -- Couple weeks after #2, below. I studied every scale promising 1 mG resolution sold on Amazon. In anything like this price range, it appears to me that they all come from one Chinese factory. Somewhat different features, different shape and size cases, yes, but on the other end of the pipeline, the same engineers and vision. This appears to be true for most (all?) Chinese products. I've run onto it in small machine tools, portable generators, and (today!) men's work jackets. Perhaps their government gives a monopoly to a single company? I don't know ... but the result is that the good things are much the same for every product of the type but if there are glitches, THEY TOO are the same. You CANNOT just 'buy one from a different company' because they're all from THE SAME company. That just wouldn't happen for items made in a free economy: Some competitor would say "We can do that better than he does" and consumers would get a real option. This is another 'externality' of the seemingly great idea of offshoring production of lower-price items, probably one most economists haven't noticed. So, after studying dozens of different small scales I bought another one of these. The battery holding issue is the only one that's fatal: The scale does come with Chinese batteries and they are indeed smaller -- just about 0.004 smaller OD than a popular U.S. brand. When the trouble starts I will get in there with a Dremel and enlarge the battery channel very slightly so the springs can actually keep some pressure on the contacts. The CAL weights for this one differ by just 1mG -- that's entirely reasonable, though I've no idea of the absolute accuracy. They now provide a set of plastic weigh pans with it -- a good enhancement. I have not yet read the manual: If their are other improvements I haven't noticed I'll update. UPDATE 2 -- over a year on and the end of the line for this scale. Basically this thing isn't practical. Two penny-ante mistakes are fatal: 1. The zero point drifts continually. My guess is that's due to it being sensitive to battery voltage -- see below. (ANY precision scale is sensitive to tilts caused by your movement tilting the floor/table -- either a VERY stiff floor or great care is necessary.) But the scale software tries to hide the drift by continually rezeroing if the change is under about 1 mG. If this were simply a ZERO change it might be tolerable but it's actually a varying calibration error. If you zero and put on a known weight you get one answer. Take the weight off, put it on again ... it'll give you a slightly different reading. The error is random in direction and increases over time. You can of course rezero before each reading but the measurement still changes in a 'random walk' manner. This isn't a very big effect -- ~10 mG perhaps -- so the accuracy is probably acceptable for many jobs but not really 1mG. 2. The batteries don't make good contact because the holder is too tight to allow the usual wimpy springs to keep them in firm contact. Hello? Battery dimensions have been standardized for decades; you can find them on the web. How any manufacturer can undersize the holder by a mM or so is beyond me, but they did. It worked okay at first, with everything factory-clean. But over time, with an invisible amount of oxidation the contact became intermittent. Cleaning battery and scale contacts makes it better for a while, but in a few days or a couple of weeks, the problem is back. Consequences in addition to zero drift are that the scale will randomly tumble digits, then resume, possibly with a different reading. Or it may flash the display 3x and go off -- 'dead battery,' except that you can push the batteries back tightly and it's fine again, for a while. Or it may simply restart itself -- the '18888888' rebooting display. Sometimes you can't turn it on. Reseating the batteries will fix that until the next time. New batteries don't make the problem go away for any longer than a good cleaning -- this unit isn't at all hard on batteries. 3. The continuous rezeroing makes it impossible to approach a pre-chosen limit. If you don't add 'fast enough' then what you add gets zeroed out. But of course the faster you add the more likely you'll overshoot. IT REALLY NEEDS TO BE POSSIBLE TO TURN OFF THE CONTINUOUS RE-ZERO. This would be an acceptable tool if it worked as you'd expect. As it is, it's intolerable after the first few months. UPDATE 1 -- a few months on: Still four stars. I have found that the only procedure I can make work 100% is to put all the weight (in my case, rifle powder) on the scale at once. I weigh the charge on another (mechanical analog) scale, dump it on the Smart Weigh, adjust if necessary by the number of granules that will give the exact weight, and if that's more than a few, dump the pan, rezero, and re-weigh. Annoying but the precision (repeatability, consistency of loads, etc.) seems to be about the max this type of instrument can deliver -- which is outstanding at the price. I will second the comments by others that if loading maximum loads one should ALWAYS confirm using another device. I think the battery contacts in these are as dicey as in the average flashlight. If it has been off for a few days I have to either remove and replace the battery to get it to come on or rap it gently on the table -- not something one should do with a scale. ORIGINAL COMMENT: First, NOBODY GAVE ME A SCALE OR A DISCOUNT for my review. And Dear Smart Weigh? It frosts me no end that about 100 reviews here are your 'freebie' people: Such a review is generally written immediately (so it's limited to features) and will on average be biased. A few such can be helpful but I always try to read what people who actually paid think about a product before buying it and plowing through dozens of reviews in order to find a few actual buyers/users is annoying. Amazon? Maybe you could allow or require such reviewers to select an option that shows their stars in a different color to make it easy to skip them when desired? S-W, please limit future freebies for new products to whatever it takes to get ten or so reviews. My application is reloading of accurate rifle ammunition: Not all of these thoughts will apply to every application. I read hundreds of reviews (total) for several similar products, both higher and lower in price before buying this one. Most 'Made in China' technical products are made in exactly ONE factory there, with different plastic cases, feature tweaks, and so on to meet the specs of the different U.S. sellers. Digital scales in the under $200 price range appear to be the same and I'll bet that they all use the same key internal parts. Thus they all have similar basic capabilities and limitations. If you want something distinctly better then be prepared to go CONSIDERABLY up in price. Pros: 1. This is among the most reasonably priced units with these features. Quality appearance, fit and finish are excellent. 2. It's compact and reasonably sturdy for a unit of this sort, the case with it is exceptionally nice. Tweezers and calibration weights are included: No line power (wall wart) option is provided -- there's no place to connect one. 3. Everything worked as advertised, right out of the box; batteries (4-AAA cells) were included and have powered it through perhaps ten hours of use without fading. 4. It weighs a lot more accurately than you'd expect in this price range. 5. The display is very clear -- easy to read even with less than perfect eyes. Cons -- Except for features most of these likely apply to all similar units. 1. It does not come with a removable pan. The pan should fit under the hinged plastic cover to allow weighing in a drafty location. 2. My two calibration weights differ by about 70 mg in 20 g.; One of them might be right but not both. Shouldn't a calibration weight for a scale be close to +/- 1 count in the last place? 3. The manual is three 2-1/2" x 4" pages of the tiniest type you ever did se ... I mean, TRY to see. The three pages in English are repeated in maybe five languages? I suspect the U.S. market is by far the largest; I don't think it's too much to expect a product for our market to have a manual that's readable with ordinary sight -- say by anyone able to read this print on a computer screen. 4. As for other scales of this type the zero drifts and any vibration puts it off by maybe three milligrams. Steady drift occurs, sometimes slowly, sometimes not so slowly. The floor where I use the unit isn't terribly rigid; if I stand up and sit back down as gently as possible the scale must be rezeroed. 5. The Smart Weigh is dumb for slow changes of weight. If I trickle powder on to it, once I get to a few granules per second (nearing the exact weight) the reading stalls -- it rezeros to counteract the increasing weight. Yes REALLY. As an experiment I added ten granules of powder one at a time with tweezers. NO CHANGE in the scale reading. Removing the pan with the powder I found that the zero correction had exactly counteracted the 0.2 gn. added weight. I found two work-arounds for this: A. When you think you have the amount right, remove the pan, pour the powder (etc.) into another container, put the pan back on the scale, rezero (press 'TARE') and add the powder to the pan all at once. The measurement will now be as close to the actual weight as the accuracy of the device permits. Add or remove your estimate of the correction to get what you want and repeat. OR: B. Note the weight of the pan before starting. (Zero, put pan on, note reading. Remove the pan. Repeat several times and use the average.) With the pan on and the scale zeroed, pour your powder on the pan until you think you have the amount right, lift the pan and note the negative reading. If it is numerically high then the actual amount is higher than the reading by that excess. For example: Pan weight determined to be 100; desired weight of powder 50 so you put on enough powder to get 50 indicated, slowing at the end. You lift the pan and find the reading is -102. The actual amount on the pan is thus 52. Put the pan back on the scale and remove what you estimate to be 2 units -- the reading of 50 probably won't change. Lift the pan again: If the reading is -100 you're good to go. When you press TARE the scale calculates a correction for the pan weight. When you slowly change the powder in the pan the scale assumes it's drifting and changed the correction amount accordingly but the pan hasn't actually changed so the displayed weight is wrong. To get around this adjust the amount of powder until the error in the correction is the same as the apparent error in the weighed amount but in the opposite direction. For example: Actual pan weight 100, desired powder 50. You add powder steadily until the reading is 48 then slow down and add a bit more: the reading is still 48 but when you lift the pan the correction is 103. You take out 1 unit of powder; if the correction is 102 and the displayed powder weight is still 48 you have the right amount. This procedure is harder to think about than it is to do. It will let you get a series of charges within about 0.02 gn. of being identical but they still aren't exactly what the display says: Scales that will do that start at about 20 times the price of this one. I use various other scales for other purposes; some of them hide small or slow changes and some don't. It depends on whether you're expected to weigh something that will move without actually changing weight (like a baby or small animal scale) which will be damped or forced to hold a reading that lasts a second or more, or whether you might want to see any change, as in adjusting slowly to an exact weight. Because this scale is likely to be used for both kinds of jobs, this ought to be a configurable feature and should be remembered across power off. Perhaps a 'DRIFT CANCEL ON/OFF' option? 6. Another reviewer (of a similar product) said that such scales typically do all weighing in one set of units and convert mathematically to the units you select so you get two rounding errors. That appears to be true for this device: When weighing in 0.01 grains, some readings cannot happen because the resolution of the weighing process is more than 0.01 gn. This is the nature of the beast -- a fact of life rather than an issue. 7.The unit shuts off automatically after a short time. I can keep a cartridge-by-cartridge pace that keeps it on, but after every so many I mark and put them away. It always shuts off then, so I have to turn it on, wait for the power-on sequence (a few seconds), reset to the 'grains' mode, and re-TARE. Auto shutoff is a necessary feature for a battery device but the time should be adjustable AND the unit should come with a wall wart power supply as an option. Such a supply probably needs to be regulated to avoid making zero problems worse. It would be nice for the unit to remember the last MODE setting across a power off.

If you've perused the lab scales on Amazon, you know there are literally thousands of them -- all of them packed with features, and very low priced. Awesome, right? No, not really, because if you've tried a few you've learned that for the most part they're pretty useless. Even models with a gazillion 5 star ratings written by the seller's many close friends can't be trusted, and one is likely to receive a defective unit -- or one so inaccurate that it's effectively useless. So imagine my shock when this scale arrived, and it worked properly. Really, my heart palpated as if I'd found Blackbeard's legendary treasure hidden for centuries in the trunk of my car. I then was stricken with a paroxysm of non-stop ideopathic sneezing, and Fearing imminent death or at least loss of composure, I called out to my girlfriend to ready the smelling salts, then I called out to my late wife Elizabeth to let her know I was coming. It was all quite dramatic! Now don't get me wrong. This is not a $10000 lab scale with factory installed telepathic control. Conspicuously absent is the ubiquitous built-in mass spectrometer function. Hell, it won't even calculate the atomic weight of whatever you're weighing. But it does accurately display the weight of your substances within a milligram or two, and that display doesn't keep changing. It's accurate enough for anything one might be using it for at home, it functions properly time after time, and doesn't fail to live up to any advertised promises. This makes it an Amazon superstar, well worth spending a few extra dollars on.
