Review: 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.
Review: 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.

## Questions & Answers

**Q: does it weigh in mg**
A: No this scale doesn't even register until you get up to 5mg, I have placed many an item below that weight on this alleged +/- .005 error rate scale, and frankly I wonder how the hell is it legal to advertise something as measuring a unit it literally has no chance of measuring. People say to place a 10g weight and then weigh the amount that is too light, but that doesn't work as far as I see for things still below 5mg, so if this thing can't detect a difference of 5mg from 0 to 5 or from 1gram to 1.005... why is it called a scale accurate to .001, sure it displays that, but thats pretty much a guess I can now see... its sad that basically to get a better scale, and not by much you need to spend 200$, and even then you won't be able to measure 1mg, just do better than this piece of junk, which I own and love, but I am annoyed at its misrepresentation of the facts, I guess fraudulent advertisement is now considered marketing huh, how the other guy can in good concience tell you this thing weight very well, i dunno, I mean its the best 20$ scale you can get, but no where near good enough for anything other than .01g measurements really, since scales need to have a 10x accuracy factor if they are worth their salt in order to round up or down to what it shows on the screen. In other words it needs to be more accurate than it displays, nearly alll .1scales are at least accurate to .05, unless their chinese garbage. But somehow this precision scale goes in the opposite direction, and alleges to display values I have no idea how it determines when it literally doesn't have the accuracy to... must be some hella funky coding for a scale that in its own manual states an error rate of plus o minus 5mg but still allege to tell you the exact mg as if that figure have a better than 1 in 10 chance of being right. Sorry the scale isn't bad for the money, I just wish they made one that actually did this, and was affordable to the public.

**Q: Has anyone used this for weighing powder for reloading ammunition? Would you recommend it?**
A: As long as you use check weights or calibrating weights (same thing just different terminology) to calibrate the scale you don’t have to worry about a thing since this one is the most accurate ones I could find other than the gempro 250 which is a $200 scale but I’d still use this one for reloading as long as I have check weights which I’ll always have.

**Q: Can it weigh in milligram precision in very small incrimental measures w/o auto-taring? A problem w/ many scales is to auto-tare tiny weight changes.**
A: Amanda:
I suggest that at 1 mg. precision, the surface the scale sits on, and the degree of level are very important.   The heavier, denser, and more solid the base is, the better the accuracy.   Vibrations also are very important.   Setting the scale on a kitchen counter top (not heavy, dense, and stable) with a refrigerator running anywhere close (say, within 10 or 20 feet) will throw off the accuracy -- probably by a few milligrams, easily.   Something heavy enough to provide a very stable base will be quite difficult to level.  While I'm not sure exactly the level of precision required, it would not surprise me if it needs to be 1 mm/meter, which would be difficult to achieve without a precision leveling device.
I can't tell you that the scale is as precise as advertised, but I do think it would be difficult to find a base in the average home that would allow you to make such a precise measurement.
All that said, I haven't shopped for a scale base that might be made for the purpose - though buying one that would be heavy enough would make it significantly more expensive than the amount you paid for the scale.

**Q: Can I weight diamonds, ruby and gold?**
A: You can anything that has more than or equal to .001 which is a miligram, very small measurement but as long as you have calibrated it right and not damaged the plate and use a level surface, you will have very accurate weight. Always remember conversion, 1mg is .001 and 100mg is .100 on this type and a solid gram is always 1000mg no matter what, different things have different densities so just because one looks more than another or less dont think its broke, unless of course the same material is weighing different . Hope this helped.

*by R***Z on 10 February 2022*

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.
