I got an S9 and I hate the way it starts slow. It stops me from getting a good breath or I hold my breath while it starts up or I have to wait to put on my mask. This part of my cpap machine is stupid. I should be able to put on my mask, start a breath then be good to go. Never had S8. Should I get ...

I purchased the S9 Elite a couple of months ago. My brother has the S9 Autoset and he enjoys it.
Should I sell or exchange the Elite for the Autoset?
What are the advantages and disadvantages of each? Thanks
