I've had a new non-rebreather mask delivered, but it's got small holes on each side. That's not right is it? I don't think the old one had them (the o2 company give me ones for free and I never took too much notice grasping for it when I needed it).

Sorry I'm being a bit vague. Having hits and the o2 isn't helping too much. Wondering if it's the mask perhaps.

Also, is it worth me buying a better mask instead of getting the free ones?

Thanks,

Thank you!

I was covering them with my fingers while using it, but think I'm going to have to look into a clustermasx.
