Pod fit getting looser after a week — normal?

I have a pod that felt very snug when new and now has a little more movement after about a week. It still works normally and I am not seeing interruptions.

Is a small amount of play something to watch, or does any change in fit usually mean the pod should be replaced?

A small change in feel is not enough by itself to call the part incompatible or failed. I would watch whether the movement affects electrical contact, sealing, alignment, or ordinary handling.

I would also inspect the contact area and the retention points for residue or wear before assuming the pod itself changed.

No interruptions so far. I will keep an eye on the contact and sealing instead of treating movement alone as failure.
