The machine ramps up to a level that is too high after about an hour and injects air into my stomach, making me bloated and waking me up, defeating the whole point of the machine. After one month of use the machine has an error that the filter needs to be replaced, it didn't even come with enough supplies to work for two months! It cost over 1,000 dollars, does not come with support, did not fix the issue, and now wants me to spend more hundreds of dollars on a new filter. Simply put, I have stopped using this machine and am down 1000 dollars. I highly recommend using a different service to find your cpap machine. This might seem like a convenient system but it is actually the opposite.
