I have bought two sets Cube 60G ac for a customer (4 cubes in total). All cubes have rattling noises inside them? Is this supposed to be normal? It just feels like a bigger plastic thing is loose inside them. What i find very odd, regarding that I have bought two sets. So I'm quite unsure, if this is normal.
After having a odysee with DPD I'd hope, that I don't need to send it back as DOA.
Sorry for this question, but I was unable to find this mentioned in the manual.
