I discovered the hard way that if you lose or crack a Xros mouthpiece, the pod itself can/will leak. I think the mouthpiece blocks the air release valve when on, which acts as a pressure seal for holes in the bottom of the pod.
However, if you keep an old mouthpiece as a spare, or borrow from an unused one, you can keep reusing mouthpieces unless they crack or get lost.
A tangent lesson is that if you don’t snap the mouthpiece back on properly, it could leak.
Thanks for your tips, Which’s sooo helpful I dont want to constantly change my mouthpiece, thats a goood way to save it!
How did you find this lesson, you’ve losed ur mouthpiece?
Great advice will keep in mind when juice is so nice I end up chomping on the tip 
Yes, I lost one. Then noticed the next morning the pod was empty above a pool of juice.
Always snap the mouthpiece back on properly. 
Good suggestion always comes from tough lesson huh 
Thanks for the tip! I’ll definitely keep a spare mouthpiece handy to avoid leaks in the future
Is it always like that? Or just happen to get a bad item
I never think about that this way and also never cracked any mothpiece, but thanks for great advice, that could definitely happen so it´s better to be prepared.
