Filled a use
Had a clock with weight problems it kept stopping with original weight this gave me a way to very the weight and keep the clock working so far it's done the job!

Not even close to accurate, way way way off. Maybe good for garbage scales.
Not a single one is accurate it’s so far off, I can’t even use it to calibrate a pocket scale. Ridiculous.

High quality and safe to use
This is a first quality item. The weights are sliding from a smaller hook then into a larger shaft. This way the weights do not slide out and remain solidly anchored. I use this system to gradually increase the weight of certain exercises and it works very well.
