The Weightrolux 500 g Black Digital Display Pocket Size Weighing Machine for Jewellery NOTEBOOK-500 looks and feels like a quality product. The scale is pretty compact, but it gives you plenty of room to place your things on it. It's got a nice rubber base that keeps the scale from moving around or sliding when you're trying to weigh something. It comes with both a battery and a power cable so you can use either depending on your preference. The buttons are clear and easy to read, and the LEDs are both bright and large enough that they're easy to see even when you're wearing glasses. You can even put the scale away in a drawer or cabinet until you need it. To use it, just pick up what you want to weigh and put it on the scale; there's no need to turn it on or press any buttons. It will automatically turn on when you put something on it. This is great because if you store the scale in a cabinet or drawer, you won't have to worry about bumping into it and turning it off while you're trying to get something out of that space later. The Weightrolux 500 g Black Digital Display Pocket Size Weighing Machine for Jewellery NOTEBOOK-500 is probably the most versatile scale you can find on this site. It doesn't just measure up to 500g, it's also capable of measuring up to 30g (0.1 oz) and has a 0.01g resolution. This means that it's accurate enough to weigh diamonds and other small precious stones.
