I have the same one you have except I have the Pillows. Been on it for 5 months, and feel worse in the mornings now than I did before I started using CPAP! All hype, and no results. Should have known that those videos they show are everyone living in a perfect world.
I have water in my heated chamber, and I still get headaches all the time.
I have pillows, and they seem to wear out after only a couple of months. I keep them clean religiously. Should last longer than that.
I have been having that problem for 5 months. I had a 17 a couple of nights ago. sometimes I am below 1.
Significant advantages if you don't have a bad cold, and than what do you do?
