I dont really like doing this. I am on o2 24/7. (Other medical issues as well) up until right before christmas I had two machines they both started acting up. I got a machine from a person on market place used that for a couple weeks until the persons sister came and got it. Found someone that works on them, we lost one machine it couldnt be saved. The one Im using now wont fill my tanks anymore and well its on its last leg sadly. So need new concentrator and filler station asap.
Please help Thank you for your time if you cant donate no worries send good vibes my way
