Will reusable pods damage my machine?

No, they will not.

Reusable capsules are slightly shorter than single-use ones to prevent damage to the blade plate. They fit perfectly and won't harm the machine when used correctly.

WayCap capsules use a reusable lid held by the machine without piercing. Bluecup and Sealpod capsules have pierce-able lids, just like regular disposable pods, and are recyclable or compostable.
