Acaia are the best coffee scale brand out there. We have tried out lots of other brands and have never found anything as good.
- Are they cheap? No.
- Are they good? Yes, very
- Are they really worth the investment? Yes definitely.
You can buy cheaper scales that are not waterproof, but in time they will die on you and you will replace them over and over again. Acaia products are built like tanks. Minimal, robust, waterproof and easy to use and clean.
If you are serious about coffee, then don't waste your time buying cheap scales, just cut to the chance and buy the best there is - Acaia.
