MAXUS Digital Milligram Scale 50g/0.001g, Compact Mg Scale with 20g Calibration Weight and Accessories, Black Powder Scale for Reloading

Needed a scale that weighed down to the 0.001.. I compared various models on here for hours and was unsure of which to purchase. Finally got this one and I am very happy with it so far. It is very accurate and stable, just make sure you are on a solid, level surface and there is no movement or vibration while weighing. Even the ceiling fan or AC draft can cause fluctuations in the weight. Electronics can also interfere with it since it is a very sensitive tool used for measurement in very small volumes.It looks like it does it the photo. It comes with some jeweler tools, and it can be powered by batteries or by the included USB cable.For the price, this is the one you want to buy.

I’ve been using scales since I was a teenager and these is the first one that goes down to 0.001: it’s so accurate and so easy to use! Best scale I’ve ever owned; I should have bought one years ago. It is perfect for weighing powders at low doses!

Tested it with 50, 20, 10, 1, .05, .02 and it read accurately after calibration. It comes with both weights needed for calibration so you're good to go with just one purchase. I bought the aftermarket weights because I need to check for milligrams for medications.

I bought this for a back up to double check powder grains reloading bullets. It’s close enough for the reloading I do. Make sure you turn it on and let it warm up for a minute or two before using. My only complaint is the battery’s run down in about 2 or 3 hours of use. It takes AA batteries but it does have a usb port to run in off electric if wanted. Great deal for the price. I would buy another one if I wear this on out

Scale accuracy is just a tiny bit off but for the most part it is a great product and it comes with many accessories. Would recommend and so worth the money.

Love it, works perfectly.

My only complaint is that the black model, the buttons are incredibly hard to read. In hindsight, I wish I ordered the silver, which would probably have been a little bit easier to read, but so far it’s been working fine as far as I can tell for measuring extremely small portions of powdered supplements for my 7 pound cat.

This scale has a potentially dangerous floating zero problem. I gave it a one star rating, because that's often the only way to get the needed info out to other customers so they can hear about a design deficiency, understand the issue, and know how they can still use this scale safely if they want to buy it. This review is a bit long, because I tried to explain the issue and the solution in several different ways.This scale is quite nice, especially for the price, as long as you avoid one potentially dangerous aspect of how this scale works. It has a terrible floating zero problem if you want to weigh out small amounts of something. The included instructions say that this scale is accurate to +/- 5mg, but it also will not register weights lighter than 9mg (SIDE NOTE- The scale I received almost never registers weights below 15mg when starting from zero). That 9mg+ spec doesn't sound like a big deal does it, because all you have to do is always weigh items over 9-15mg in weight and you are good to go with +/- 5mg accuracy right? Wrong. As long as you are putting something larger, like a marble or a stick of gum on the scale, or if you are adding 50mg items one at a time, this scale is excellent for the price, and 95% of the time it will give you a number that is within 5mg of the actual item weight, even with the scale zeroed out before adding the item you want to weigh. There are some reviews of this scale on youtube that show this exact type of testing, and this scale does an admirable job of being consistent. That was why I decided to buy one for myself.However, a potentially dangerous situation comes into play if you are trying to slowly weigh out something very lightweight, while also starting from zero. Zero, as in “nothing at all on the scale” or zero as in “adding something to a small tray that has been first zeroed out with a press of the TARE button”. The floating zero design failure of this scale will often rear its’ ugly head if you are wanting to weigh out things like tiny beads, small plant seeds, a supplement powder, reloading powder, or a chemical powder for a chemistry experiment. These are tasks people often want their milligram capable scales to perform. That's where this scale can be wildly inaccurate if you don’t do things a certain way. I mentioned at the beginning, the literature says this scale will have a hard time reading anything lighter than 9mg. What it doesn’t say is that if you start your scale at zero and then add 8mg of something, then add another 9mg 2 seconds later, then add 6mg two seconds after that, and then 9mg again, the scale will often still read zero, because all of those individual additions were each 9mg or less, with a tiny one or two second delay between adding each one. In other words, if you are wanting to weigh out 50mg of supplement powder and you start the scale at zero, but you add that powder to the scale too slowly, the scale might miss the addition of powder once, twice, every time, or never depending on how fast you added small amounts and how small each amount was. As a result, one time you can get a total of 50mg, you can weigh the same powder again more slowly and get a total of 34mg (because the scale will miss a few of the lighter weight powder additions at the begining), or you can add it even more slowly and in tiny amounts and the scale will always remain at zero.The only way I found to completely avoid this situation, is to make sure your scale never starts at zero when weighing very light things or when weighing things out very slowly. If you want to weigh out 30mg of supplement powder for instance, turn on the scale, then add the included black plastic tray to the scale but don’t press the TARE button and zero out the scale after doing that like you would normally do. Just begin weighing out your powder. As an example, if I put my empty plastic tray on the scale it weighs 3.090g (3090mg). If I want to measure out 30mg of supplement powder I just start adding powder to the tray until the total displayed weight becomes 3120mg (3090mg tray + 30mg of powder). If I do it that way, everything works great and the powder will show an accurate weight even if I add it to the tray slowly or in small amounts. If I instead start the scale from zero, (or tare it to zero before adding the powder) I will end up with some random result between 0mg and 30mg for my total supplement powder weight and the displayed weight will be different each time depending on how fast I added the powder to the scale. That could be very dangerous, especially if you want to fairly accurately weigh something like reloading powder, a chemical powder, etc.The image I included with this listing shows little pieces of cut up plastic that I made. Each piece of plastic shown weighs between 6 and 15mg. My scale in the image was started out at zero before adding the plastic pieces. They were placed on the scale one at a time, with about a 1-2 second delay between each one. As you can see the scale still shows zero. All those pieces shown on the scale actually weigh a total of 172mg (or 0.172g). That’s what I mean when I say this scale has a “floating zero problem” when dealing with small weights. This scale will consistently show the proper 172mg weight of the plastic pieces if they are poured onto the scale rapidly or if they are slowly added one at a time to a known weight (not zeroed out via the TARE button) already sitting on the scale.
