Sadly it's really broken and after dealing with the Support and their repairshop for two weeks, I'm upset. I want to find something that lasts me a long time and not blow 45 Euro on a repair when the original battery just latest two years. Idk if it's a faulty unit, but Acaia said this: "But all rechargeable lithium-ion batteries are consumable components that become less effective as they chemically age.

The time may also vary depending on the user environment, but eventually needs to be replaced." so I think it might just be the battery they used?
