Review on πŸ“ MAXUS Dante Digital Milligram Scale 50g x 0.001g: Accurate Weighing with Calibration Weight, Scoop, Pan, and Tweezers - Silver Edition by Samantha Salazar

Revainrating 1 out of 5

A good price scale if you're careful to avoid a potentially dangerous floating zero.

This scale has a potentially dangerous floating zero problem. I gave it one star because it's often the only way to give other customers the information they need to know about design flaws, understand the problem, and learn how to use the scale safely if they choose. Buy it. This review is a bit long because I tried to explain the problem and solution in different ways. These scales are pretty good, especially for the price if you avoid one potentially dangerous aspect of how these scales work. It has a terrible floating zero problem when you want to weigh a small amount of something. The instructions provided say these scales are accurate to +/- 5mg, but they will also not register weights below 9mg (NOTE: the scales I received almost never register below 15mg, starting from zero). The 9mg+ spec doesn't seem like such a big deal as all you have to do is always weigh items over 9-15mg and you can work with an accuracy of +/- 5mg right? Not correct. As long as you're putting something larger on the scale, like a ball or gum, or adding 50mg items one at a time, this scale is great value and delivers 95% of the time. Enter a number that is within 5 mg of the item's actual weight, even if the scale is zeroed before you add the item you want to weigh. There are several reviews of this scale on YouTube showing exactly this type of testing and this scale does a great job. That's why I decided to buy it for myself. However, a potentially dangerous situation arises when you try to slowly weigh something very light and even start from scratch. Zero, as in "nothing at all on the scale" or zero, as in "add something to a small tray that was first zeroed by pressing the TARE button". The lack of a floating zero in the design of these scales often fails when you want to weigh things like tiny balls, small plant seeds, supplement powder, refill powder, or chemical powder for a chemistry experiment. These are tasks that people often want to do with their milligram scale. This is where this scale can be very inaccurate if you don't do things a certain way. I mentioned at the beginning that the literature says it will be difficult to measure anything lighter than 9 mg on this scale. What he doesn't say is that if you start from zero and then add 8mg of something, then add another 9mg 2 seconds later, then add 6mg two seconds later and then add 9mg again, the scale is often still zero indicates. because each of these individual additions was 9 mg or less, with a tiny delay of a second or two between each addition. In other words, if you weigh 50 mg of a powdered supplement and want to start the scale from scratch, but add that powder to the scale too slowly, the scale may skip adding the powder once, twice, every time, or never, depending on how quickly you added a small amount and how small each amount is. This allows you to get a total of 50mg at once, you can weigh the same powder again more slowly and end up with a total of 34mg (as the scale will skip some additions of the lighter powder in the beginning). or you can add more more slowly and in small amounts and the scale will always stay at zero. The only way I've found to avoid this situation entirely is to make sure your scale never starts from zero when weighing very light things, or when weighing things. So slow. For example, if you wish to weigh 30mg of a powdered dietary supplement, turn on the scale, then place the supplied black plastic tray on top but do not press the TARE button and then zero the scale as usual. Just start weighing the powder. For example, if I put an empty plastic tray on the scale, it weighs 3.090 g (3090 mg). If I want to measure 30mg of a powdered supplement, I simply add powder to the bowl until the total weight shown is 3120mg (bowl 3090mg + 30mg powder). When I do it like this everything works perfectly and the powder shows the exact weight even if I add it to the bowl slowly or in small amounts. If I instead start the scale from zero (or tare it to zero before adding the powder), I'll get a random result of 0mg to 30mg for my total weight of the supplement powder, and the weight shown will be different each time, depending on the situation how quickly I added the powder to the scales. This can be very dangerous, especially if you want to weigh something like reloading powder, chemical powder, etc. fairly accurately. The picture I've included in this listing shows small pieces of cut plastic that I made. Each piece of plastic pictured weighs between 6 and 15 milligrams. My image scale was restarted from scratch before adding plastic parts. They were weighed individually with a delay of about 1-2 seconds each. As you can see, the scale still reads zero. All parts shown on the scale actually weigh 172 mg (or 0.172 g) together. That's what I mean when I say these scales have a "floating zero problem" when working with small weights. This scale will always display the correct weight of 172 mg pieces of plastic when they are quickly dumped onto the scale or when they are slowly added one at a time to a known weight (which is not reset with the TARE button) that is already on the balance is located.

Pros
  • Good thing
Cons
  • Hard to remember, but it was
