I really liked this mask that I tried. And I have tried many over the years that were uncomfortable, leaked air or just wasn’t good quality. This mask has held up wonderfully. Still comfortable and no leaks. I highly recommend it for any cpap user.

I have had my In Inogen for two and half years, it gives me the freedom to do whatever I want. Go shopping, meet friends for lunch even spend the day quilting with the local QOV group. I can always rely on this little machine. Recently I got a message that the machine was overheating. I called Inogen, they answered right away and a representative had me run a simple test. She said the machine needed replaced. The new machine arrived in 4 days and the next day UPS came back to pick up the old machine and return it to the company. I didn't have to leave the house! Great service.
