Smart Weigh GEM20-20g x 0.001 Grams, High Precision Digital Milligram Jewelry Scale, Reloading, Jewelry and Gems Scale, Calibration Weights and Tweezers Included

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.

This is a great little digital scale. I make jewelry, so I have to measure in both grams and carats frequently for precious metals and gemstones. This scale is perfect, as it weighs up to 50 carats (20g) with accuracy to plus/minus 0.001g. I've found it to be very accurate, though if using the separate tray that comes with it and the TARE function, I generally do several measurements to be sure. Do ensure that you place the tray on the center of the plate, or you can get inaccurate readings. Always make sure the scale is placed on a flat supportive surface, which also helps ensure accuracy. Calibration is very easy, and this should be done before the scale is used. If you have lost the manual, I have posted the process from the user manual in the questions section since a couple of the answers were not correct for the 20g model of this scale. I noticed that some reviewers have said the scale is flimsy and easily broken. I have not found that to be the case, but I don't keep the scale itself on my workbench. Instead, I keep the scale and the included components in the original case as it is lined with form fitting foam. I then store it and my larger scale on a separate shelf unit next to my bench that does not get jarred. If you keep it in the box, you'll also have less chance of losing the tiny components that come with it along with the second calibration weight and the handy user manual! I've used the scale for several months now, and my judgment is that it is a keeper. The manual also is in good English (rather than a bad translation from another language), another bonus! The instructions are in several other languages, including French and Spanish.

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.

More accurate then my $170.00 OHAUS YJ103 Jewelry/Gold Scale, I compare the weights I was getting against the YJ103 Digital scale and my trusty OHAUS Made RCBS 10-10 Beam scale and the readings were close to perfect if you plan on using this to weigh in Grains for Reloading. Now the reason I gave it only 4 Stars is because of two Minor things. #1 It has no Built in Bubble level nor can you screw the 4 Pads/Feet on the bottom to make it level, which is a necessity if you want accuarte weights, I plan on buying a small piece of flat Marble Floor Tile from Lowe's or HD to set this little bugger on and to that I will install 4 little pads that can be adjusted in or out. #2 The weighing area this scale is about 1.5" round (About The Size Of A Checker Game Piece) which has a stamped impression in it the size of a Quarter, which is just big enough for the TINY TINY pan they include in the box, I tried to use the Bigger Plastic Pan that came with my OHAUS and it fit but was unstable because of the recessed stamped impressing in the middle, I found that if you moved it (Bigger Pan) a tiny bit the readings were all over the place, So I'm going to search and see if I can find a nice little pan that will fit so I can Trickle Powder into it. Other then that this little scale is worth every Penny of the $16.00 I paid, In fact I wish I would have purchased this Brand instead of the JUNK OHAUS I'm now stuck with and DO NOT TRUST.

Very, very pleased with this scale. Like mentioned in many thorough reviews, there are little issues BUT I found tips to bypass them (see below). I use the scale to measure micro dosing for psylocybin (125mg +/- 5mg). Trickling/reloading works very well. It's all plastic so manipulate with care. Do not exceed max weight capacity, and always lay flat. If batteries are low, results may become inconsistent. Calibrate before each use for more accurate results. Measure more than once for more critical readings. Do not expect accuracy below +/- 5mg. If you want/need that, then pull out your wallet $$$. Issue 1) The calibration weight (2x10mg) do not fit upon closing the lid. (A design flaw). Yet for consistency, air flow must be accounted. As a result, calibration will always be "off" when closing back the lid. Furthermore, closing/opening the lid does affect the reading sometimes (+/- 6 mg). It shouldn't but it does. Solution: Calibrate the scale using the lid OPEN, then leave the lid in that upward position for the subsequent measuring needs. To eliminate the airflow variations, use a clear container (like a glass bowl or tupperware) to cover the entire scale - - with its open lid. No part of the scale should touch that container. This acts like a dome and now blocks any airflow. You will still be able to read the digital screen as it is bright and easy to read. This "DIY dome" also increases the capacity to weigh "taller" items that would not fit under the original lid in the first place. Nice bonus :) Issue 2) These little scales tend to read more consistently past a certain amount of minimum weight. Here, past 5 mg seems a good starting point. Solution for pill size quantities (in my case 125mg), TARE the included tray as well as a nickle underneath it. Together, they weigh just over 6mg. Once tared, the scale reads "zero" but the inside mechanism is preloaded, which provides even more consistent results. I am very happy with it. Negative reviews are likely related to people who do not handle/calibrate/setup appropriately.

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!

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 🌸

Es más precisa de lo que esperaba en cuanto a los mg, aunque si es cierto que puede tener un error de +/- 0.003 mg que la verdad por el precio que tiene y por lo bien que está me parece minimo. Viene en una caja con : la báscula, un par de pesos de 10g, unas pinzas y un cacito metalico que viene muy muy bien para pesar cosas en polvo. En cuanto al funcionamiento es simple, la pantalla esta bien iluminada y la verdad que yo recomiendo no equilibrarla ni nada así porque ya viene hecho, e igual es peor mover los parametros. La calidad de los materiales no es la mejor del mundo asi que hay que ser delicados, pero por el precio es lógico. Poco más que añadir, la recomiendo si es para un uso personal y no profesional.
