rubbish,they gave false readings.

Muy buen producto

I bought these, like many others, to check the accuracy of my home scales. I checked them on our kitchen scale and if they were the exact weight as shown on them, then the scale said they were bang on. That's assuming that my kitchen scale is reading correctly. Either way they were close enough for me to use.I'm now using these weights to calibrate a 3D printed filament scale made from a 1kg beam load cell, an Arduino Nano board and an OLED display. Nice to get a good idea as to how much filament is remaining on the spool before committing to a print.Good value for the money.

I like that this version comes with a protective case. I do not use the scale everyday so it is nice to keep it well protected. I recommend this product.

Strangely enough, I got this to use for a baking scale. And while I haven't had the opportunity to actually do any baking, I was able to run some tests by weighing some rather lightweight items, and zero-ing the scale for a "container" then adding the lightweight items and their weights totaled exactly what they were previously. It's not like I'm a gold (or drug) dealer so the convenience of the size being small enough to fit into a pocket isn't all that relevant to me. However, since I live in a small apartment (about 600 sf) keeping things as minimal as possible is a priority. So I'm rather happy with these and looking forward to baking a cake from scratch and getting all of the ingredient measurements exactly correct :)

As a hunter who often goes on long journeys without carrying much, this kit is convenient to pack. All types of things happen when I’m out in the forest. Having the ability to case my own bullets adds to the experience of self reliance. The digital scale helps me measure precisely and it’s easy to wipe clean. All the necessary tools are included which also helps me as I’m forgetful. If you’re not accustom to reloading your own bullets, this kit comes with easy directions that include basic pics. If you’re like me who might lose the manual, the instructions are also written with simple pics on the interior cover of the box. There’s no way you can miss it. Very good product.
