I have been using the Quattro mask for 7 years now. I like the mask but over the years I have now developed a small bump in the middle of my forehead due to the two pressure points from the T-bar center where no pressure is applied. In other words where the mask touches my forehead is fine but in between those two touch points, I have now a small bump on my forehead which is very annoying as it doesn't go away. So as a result I tried new masks. My results are confusing and interesting at the same time. I should point out that my machine is set to a pressure of 15 to 18 by the doctor for the last 7 years.

Here is my old mask:

Here are the machine readings (disregards the time stamps as my clock is out of sync):

Here is a special mask machine readings I really wanted to try and I am really impressed by that mask:

If you compare the the 3 readings it is very interesting...
![Question :?:](./images/smilies/icon_question.gif)
- The new mask has a much lower leakage but the pressure is constantly at about 16.
- The old mask has an extreme high leakage and the pressure varies from 0 to 12.
- The special mask has a leakage right between the 2 other masks and the pressure varies from 0 to 8.

Having read previous posts here about pressure vs flow and longer test periods, I wanted to share those results and get some feedback as I will test them more over time. I have tested those masks now each for 1 night each and more tests will come but I am really surprised about the differences between those masks in pressure/flow, which is also the reason why I posted a picture of each mask to avoid the debate about nasal, t-bar or full face mask, etc.

Any feedback is welcome! Thanks in advance.
