WEIGHTMAN Milligram Scale 50g/0.001g, Compact Mg Scale with 50g Calibration Weight, Red Powder Scale for Reloading

Just as advertised and feels very durable, but I will see how it performs.

So far so good. This little scale is a lifesaver for what I want to do. 400 ml weighing out potassium chloride. Impossible any other way. I just received it so I may upgrade if there are issues. User freindly.

Very convenient calibration weights stored under plastic hood for regular calibration and accurate. Love this thing.

So this scale needs to be plugged into a direct power source like one of those portable power banks you use to charge your decices or just a regular usb port. It does have USBC which is awesome. So I used this for some time with batteries and will jump around a bit, once plugged in it stopped the bouncing. I finally bought a balance beam scale thinking it's going to be more accurate BUT this scale matched the balance scale .01 of grain and up, point for point. I was really pleased to see how well it really performed! Just make sure you do your trial with the two 20 gram weights. (Read the manual) For the price of this scale it works fantastic!

Very nice device, for the price you get excellent value. It's not like a $200 laboratory scale, but it also does not take up too much room. It's good enough for what I need. The biggest selling point to me vs the other ones I already have is that you can power it off USB, I have a couple similar scales that are battery only, and the batteries are dead right when you need to use them a few times a year. I do have some solar USB power packs or just regular USB wall warts that avoids having to deal with batteries when using this. It did come with a pair of fresh batteries though, I just did not install them, will save them for my tv remote. I try rechargeables for tv remotes, AAA NiMH, and I try to use them as much as possible, but they self discharge within a month or two and need constant recharging for a few hours every month or so, so having non rechargeable batteries too helps while they charge.
