“5 stars for the black cartridges; however I ordered a 2-pack of the red cartridges and neither of them fit properly in my Mi-pod. I have 2 devices and tried them in both of my units and each time they were so loose that they wouldn't snap in properly. I used them anyway, just couldn't pack them anywhere. Also since they are red it's harder to see that they battery is going low because the light goes from purple to red. Just my personal preference to use the black cartridges.”
