@Rafique wow 4 out of 10 is quite high. For me it's like 2 out of 10 maybe. It's not as common but the pod basically becomes unusable. And at 50 bucks each it's not ideal that the terms of return are so strict.
Agree @HiddenInTheClouds it's just too much hassle I have thrown the pods that have me problems awat, I'm not really worried about returning them just thought I'd let twisp know.
