OSITO Oxygen Concentrator 1-7L/min Adjustable , 24h Continuous Flow ,90% Purity ,Low Noise ≤45dB SYK-608

I’m very happy with the machine
Works great good air flow and super quite

First the price is awesome and the fulfillment was excellent as well. I am not a full time user, I primarily use it for headaches so the couple of times I have used it i can provide some feedback. The one thing that bothers me is the higher the pressure the lower the o2 level. It is at 35% when o2 flow is at 7. The rest of my feedback is just recommendations. Masks should be a standard full face or cannula and provide a longer hose. The mask provided is not usable. Second feedback is it would be nice if wheels were available. Even with the unit being small it would make easier. The older we get the more we need easy. Thanks much

I like this product so much I bought a second one. I keep one in the bedroom and the other in my family room. Since I do fall asleep on the couch very often. It’s relatively quiet. Very simple to use. I like the replaceable air filter and the fact I can add water to help keep my nostrils moist. The easy to read screen is also a big plus. Overall I give this 5 Stars

I've only used it twice, afraid of it to be honest. I know too much oxygen can destroy the lungs worse than they are so I only use it when I am waaaay low on energy. I use it for like 20 to 30 minutes and go on with my day.

Good machine at great price. Seems to be running excellent
