Delivered quickly and everything is intact. The seller took into account all my wishes.

I love a and look forward to my 13 minute session daily. My head feels clear afterward and my expansion of my lungs makes it feel easy to breathe. I have more energy throughout the day. I wish there was a mask that fit better. I do a HIIT training on my elliptical at the same time. I sweat and the mask moves up and down. A higher quality mask that doesn’t move would be great. The oxygen generator takes about an hour and 40 mins to fill the bag. I turn it on before I go to bed because it has a timer. I set it for the proper time and it is ready to go in the morning when I wake up. The big problem is it is a manual timer so if you forget to set the timer it will continue to run and blow apart the bag like it did mine. it would be nice to have an automatic timer so when you start it it would stop without doing that or have a pressure switch that knows when it is full. All in all it does the job I crave the oxygen. Now have to buy another bag.
