Brand New machine in March. Used it 4 times and decided its not for me. Couldn't return since I paid dearly for it. $1600 plus the Dream silicone nose mask.
I would suggest cleaning the mask & tube. Other than that the machine is new and still have the papers. I've read online it can be sold if the purchaser has a prescription or I can sell it to a buyer online. I wanted to try this first. Hoping there is someone out there needing one that would rather not pay $1700 for the machine. Pick up in Hays Kansas
