Smart Weigh GEM20 High Precision Digital Milligram Scale 20 x 0.001g Reloading, Jewelry and Gems Scale, Silver

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 🌸

It is very precise and good. I used it it weigh gold bhasm.

For its price, its doing my job just fine. Value for money.

Value for Money, Nice device & Easy to Use.

The unit was not working. On switching on, zero on the scale didn’t appear. So no calibration possible also. It is used for weighing gemstones to the accuracy of 0.000 cts. So returned the product.

Acuuracy , easy to use

As given in description it is not 1 mg accurate. It cant even ready 10 mg wight accurately!

Build quality is good. Robust. The measure is accurate too.

No todo lo fabricado en China es de mala calidad. No todo lo que produce China es malo, depende mucho del país para el que trabaje y de lo que le pague por hacerle el producto. Alemania es el país que mejor le paga china, pero a cambio le exige mucho en lo que a calidad se refiere. La balanza es de una precisión enorme, yo la he adquirido con la finalidad de dosificar medicamentos, concretamente el Tryptizol 25 mg. y el Diazepán o Valium 10 mg. para el trastamiento por depresión neurótica. Pues bien, al pesar una pastilla de Tryptizol a dado un valor de 0,125 gramos. De esa cantidad 25 mg.son del principio activo, la amitriptilina (lo pone la caja del medicamento,), los otros 100 mg.son los aditivos que le ponen al principio activo y que en gran número de pacientes son perjudiciales para el organismo. De todos modos esos aditivos vienen en los prospectos del medicamento, es obligatorio, pero no pone la cantidad de cada uno, en el caso del Tryptizol lleva nada más y nada menos que doce componentes más añadidos al principio activo. Recomiendo esta balanza por su gran precisión, exactitud y calidad en especial para aquellos enfermos que necesiten dosificar medicamentos, pero no creo equivocarme si aconsejo que sea empleada en laboratorios de farmacia o de otros tipos de investigación. En la opción gramos la que yo he recibido el error es cero. Manuel Pellejero Samitier.

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.

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!
