Smart Weigh GEM20 20g x 0.001g Milligram Scale with Accessories

Weight Tracking: This is pretty accurate, from my own testing there is about a 1-3 mg deviation in accuracy which is pretty impressive for a cheaper scale. I measured the accuracy with a mg weight set I bought alongside this one. One must assume that the weights themselves are also not 100% accurate, so this scale could potentially be even more accurate then that. Usefulness: This is pretty useful for anyone needing to measure things with fairly accurate results, but does not want to spent hundreds of dollars on a scale. Informative: The scale offers a number of different weight options, it is important that you read the manual for properly taring and all of that. This scale is very sensitive, so following the manual is important. Speed: It's a bit on the slower end, but that's ok it doesn't take long, but it is a good idea to give it a second or two and try not to breath on it because it's very sensitive and even a breeze could potentially offset the weight by a +/- 1 mg. Size: It's compact enough and easy to transport, the packaging is magnetic which is nice, so be careful to make sure you realize this and don't tear up the packaging in an attempt to open it.

Works well. Still holding strong after a year+. Hasn't given out the way other affordable scales often do. Although I did buy this when it was cheaper, so it was better value, I think it is still worth the money if you need a decent and fairly precise scale without getting some $300+ scientific scale. If you need consistent guaranteed accuracy in roughly increments of 5-10mg, this is great; if you need insane precision, this is not it. Outperforms most others I've used in this price range (which isn't a giant sample but I've tried a few others).

This is a fabulous High Precision Digital Weight Scale. I am most pleased I can push a button, weigh my measuring unit, then hit the button on the left, which subtracts the weight of the weighing tray so that the screen reads 0.000 g and then, since I need to have precisely 0.015 grams of a powder, easily get this precise amount. Then, with a large flip open cover, I can leave the weighing tray on the unit, my weighed power in the weighing tray, put down the cover to protect the powder, and have this meager dosage ready to take with my 120 mg. dosage of Armour Thyroid medication for my thyroid at 4:00 a.m. I don't even have to find my bifocal glasses to see anything! Doing this, this way, saves me over $50 monthly. , I couldn't have asked for a better product to assist me. I did a lot of research to find the proper scale, and this one easily meets all my powder needs for any of my multiplicity of supplements where the dosage is 1/8th of a teaspoon or less up to 20 grams. Currently I use other teaspoons which I level off with a knife. And, once I figure out how to use a drop, a smidgen, a pinch, a dash or a tad, I will be using those measuring tools with this unit as well. Additionally, I could use this unit because it also weighs oz, ct , ozt, dwt, gn, and utilized high precision sensors to ensure the advanced accuracy of 0.001 grams and capacity of 20 grams. The set comes with a set of tweezers, weighing tray, with a dipping area if you are working with fluids, and two 10 kg calibration weights. The unit also features a flip open cover to protect the scale's platform besides a back lit screen for easy visibility. In fact, since the summer of 2014 I have been having hypothyroid issues, where my dosage of Armour Thyroid has had dramatic swings, the loss of 40 lbs. over 3 months, the weight gain of 40 lbs over 2 months, and intense chronic fatigue, etc. Then, when I learned (no benefit of my MD or Pharmacy) to separate iron and magnesium by 4 hours before as well as after my thyroid pill consumption, my thyroid medication settled down to more normal numbers. But, my thyroid is still in a state of flux. I also commenced dicing a raw beet a day to assist my thyroid as well as eating 2 Brazil Nuts daily for my selenium level. This caused my thyroid medication to be reduced to 135 mg. daily from 150 mg and may again decline as my system gets regulated with beets, Brazil Nuts, and no magnesium or iron within 4 hours either side of my thyroid medication. Yet, this dosage of 135 mg. is not a normal one and becomes 2 prescriptions, and thus costs me for 2 prescriptions. Got to love the drug companies who've really figured out how to .... I refused to purchase the 0.015 mg dosage (the size of a tiny nail head). But, I've a goodly supply of 300 mg thyroid medications, which I was slicing into 1/2 or 150 mg which would cost me for 1 prescription and last for 2 months, thus saving me $50. My dosage used to be 90 mg. This kept my medical cost reasonable. So, I ground up the excess supply into powder. Each evening, I use my Heathrow Scientific HD 15909 Spatula with Flat End and Spoon End, 9" Overall Length, to select a wee amount of this powder, and put it in a measuring cup on this scale. It is so easy to get precisely 0.015 grams. If I need tweezers to select a smaller amount of powder, I do that as well. One of the greatest features of this Smart Weigh is the fact you can easily weigh the tare (weighing tray), and once you have that, that tare weight unit is known by the system. Then, push the button on the left, your scale will read 0.000. This makes it so easy for me to read precisely 0.015 grams. I truly hope this information is of help to you. And if any of you have thyroid issues, it doesn't matter which thyroid medication you use, the thyroid medication will not work correctly unless you separate by 4 hours your taking of magnesium or iron, and iron is in everything except for milk products and a few candies. Even yogurt which has fruit on top has iron in it and will interfere with your medication. This period is 8 hours and not a millisecond less! I'm so glad I made this purchase and it has a place of honor on my kitchen counter.

I needed a scale more measuring small amounts of vitamins and supplements and this had decent ratings. For a $20 scale, it really is phenomenal, however the general build quality is a bit lacking (again, this thing is only $20) Upon arrival, the scale was jumping all over the place with no weights on it and several different error messages kept popping up. I attempted calibration, which wouldnt work either. I then noticed the weighing plate was stuck to i gently pushed and it kind of "popped" and seemed to work a little better. Now it would at least register when you put a weight on it, but again, it was terribly off and kept jumping around. As it turns out, the weighing plate was tilted or bend too far to one side and was catching on the area around the plate. After taking the tweezers and gently bending it to the center, the scale now functions very well. tl;dr: Scale needed tweaking to work properly, now is an incredible and accurate scale.

I'm really happy with the service of Better Basics LLC who sell this scale. I purchased my original scale about 22 months ago and it functioned very well for 22 months after which time it failed. I called better basics and they helped me try to find a solution and when we couldn't, they sent me a new scale. They were very friendly and promptly sent me the new scale. I couldn't be happier with their service. Thank you

Okay so this scale was smaller than I thought it would be but it is really accurate. The accuracy is spot on. I use this scale to weigh out gems for jewelry production. The pros are it is small and is very accurate and has lid to protect the base. Not to mention the amazing customer service from the sales team. It arrived 1 day early +++ in my book .. thank you guys! Now that I sang the praises of this unit let me provide the other side of things. This is important in order to give an honest accurate review. Cons: * The size of the scale and weighing surface. For those of you who are looking to weigh the ct of gems that are still threaded this is not for you. the surface will not allow for that. * Display color This is not a major issue and is still able to be read but it makes it a little harder with the display color and it takes a toll on your eyes after extended use. This not a great idea for those who are using it for extended times. * Size of weigh pan It really is not much of help when it comes to gems it wont hold much. * Very Sensitive! This is both a pro and con but it takes nothing to change the weight on scale something as simple as the angle of scale when weighing an item. I noticed the weight difference during one project when i accidentally had a tiny zip-lock bag under the scale that the gems came in so make sure nothing is under the scale. ;) Over all thoughts: Great scale just could use a different display color. And this is NOT usable for food way to small. Weight pan is pretty nice with a spot to pour ( Seed bead) size gems back into bag or container. Would I buy it again? Maybe it depends on what I am using it for. For what i use it for now? No due to the small size and display color. for something to be used time to time? Oh yes defiantly it is a great scale. Just the wrong tool for the job in my case.

I've had this for 6 years now, it's continued to work fantastic. It's pretty high quality and have used it to measure out peptides many times. I don't use it much, and might have had to replace batteries once since I've had it, so great battery life. It's small and lightweight, can fit in a coat pocket or any drawer. Super easy to use and calibrate. It's increased by 50% since I bought it, sigh. I recommend it.

Other than books, this is the first item I’ve ordered from Amazon. From start to finish it’s been a horror show. Amazon’s packaging and shipping system leaves much to be desired. But that’s another story. As to the scale itself. When it arrived, I first looked at the data on the box. Among other things, it says the contents include two 10 kg weights, used for calibrating the scale. Hate to be the bearer of ill tidings, guys, but a “kg” is a thousand grams. It would be hard to use them on a scale that only measures to 20 grams in the first place. The weights are titularly 10 grams each. I say “titularly,” because, as we’ll see, there is no reason to believe they actually weigh that. The box info also says there’s a set of tweezers included. Hold that thought. Next I opened the box. Included was the scale, the two weights, and a so-called instruction manual. But, alas, no tweezers. There’s a molded cavity where they’re supposed to be. But whoever boxed this scale at the factory must have thought they were an unimportant part of the package, so left it out. The manual, itself, is somebody’s idea of a joke. First off, it’s written in tiny characters. Just guessing, I’d say about five point type at best. Even with a magnifying glass it was hard to read. And the information is self-contradictory. Under the heading “calibration,” there are multi-stage instructions on how to calibrate the scale if necessary. Among them is a caution to check that the readings given fall within the allowable tolerances. “See chart below,” it says, to find out what they are. There is no such chart. The closest is a line in a box that provides specifics about the scale, that says: “Calibration: Self-calibrating.” Uh, huh! Let me get this straight. Smart Weigh provides half a page of instructions for calibrating its product, and then tells you it isn’t necessary to do so. The real crux of the matter is that it certainly is necessary. Turning the scale on, with the setting in grams, the screen---which is very readable, I’ll give them that---zeroed out as it’s supposed to. I then put one of the weights in the center of the pressure plate. After bouncing around, up and down from 10.000, it finally stabilized at 9.999. That’s a full milligram off (unless you measure the way the Smart Weigh does, in which case it’s 9 grams). Repeating this with the second weight was worse. After bouncing around from as low as 9.994 to as high as 10.001, it finally stabilized at 0.996. Four milligrams off (or 4 grams if you prefer). An earlier review at this site suggests that outside conditions cause the fluctuations, and that the problem can be solved by lowering the cover. This doesn’t work when using the weights, because they’re too tall and the cover won’t seat properly. More to the point; with nothing on the pressure plate, closing the cover changes the reading by more than two grams from the zeroed setting. That’s actual grams, not the company’s version of measurements. Next I tried calibrating the scale, using the company instructions. This entails, as a final step, stacking the two weights. Reaching that point, I dutifully placed the second weight on top of the first. Bounce, bounce, bounce, bounce, bounce until finally stabilizing at 19.994. Now six milligrams might not sound like much. But, when you’re measuring doses of herbal medicines (my intended use) that could be a crucial difference. Especially as there’s no way of knowing if it’s really only six off. From all this we can conclude one of three things. One or both of the calibrating weights are wrong, or the damn scale doesn’t work. I’m not in a position to say which. But none of them is acceptable. I returned it to Amazon. And would be leery about ordering anything else from this company.

Da ich im 0,01 g Bereich genau messen wollte und mich nur diese Nachkommastelle interessiert, habe ich mir eine Waage gekauft, die auf 0.01 g "genau" wiegen sollte. Aber dieses Gerät war für mich unbrauchbar. Es schwankte bei jeder Messung um 0,02 g vor allem bei sehr kleinen Messobjekten war das Gerät absolut unbrauchbar. Ich habe die Waage zurückgesendet und nun diese Smart Weight 0,001 g gekauft. Dieses Gerät entspricht meinen Anforderungen vollkommen. Nach Ein paar kleinen versuchen, habe ich eine maximale Abweichung von 0,002 g festgestellt, für meine Zwecke also irrelevant. Und die Waage fängt auch schon bei sehr kleinen Objekten an zu messen. Nach meinem Test gestern reagierte die Waage schon auf ein 0,006g "schweres" Gewicht. Entgegen einer anderen Rezession, passt bei mir die Wiegschaale perfekt drauf. Es gibt im Messergebnis absolut keine Abweichung zwischen dem Messen auf der Schaale und der Messung direkt auf der Messfläche.

A good product but unfortunately it cannot measure down to the milligramme. I needed to weigh out medication down to 2 milligammes - the scale cannot pick up such small amounts accurately. The seller provided an excellent service and I had no problems returning the item. Thank you to the seller for such prompt and professional service!

These are excellent, easy to use, clear display, maybe not the most durable, quite delicate, but perfect for weighing very small supplement doses.

Such an amazing product i found after searching for almost 6 months, i recently got to know that this product is inported from USA no doubt why this product is so promising, highly satisfied 🌸

Lo uso para pesar medicamento y me ha servido mucho.
