I need supplemental oxygen while sleeping.. I hated the thought of the big bulky equipment in my bedroom plus not easily to bring with me when carrying.. also health insurance wanted to much for a monthly rental and I needed it long term.. I found this little gem and I can carry with me when visiting family and I’m happy with it.. it’s not super noisy but you will need to get use to the sound if your use to sleeping quietly .. it has a continuous flow and you can change the percentage .. the light is bright on top when running so I covered with a small cloth .. I’m anxious to see how long it lasts I’m about 2 weeks of usage

I've tried some other units n they were average but this one has been great n reliable tysm 😊
