Really your service on this machine is very very bad and return or replacement also not processed till now already i was raise the request for return and replace but you could not processed

This is not working product do not purchase

The media could not be loaded. This machine not producing oxygen. I called Amazon for Waranty but they are saying we are helpless. Then they should not give marketplace to such a fraud items.

worst product. it's not a oxygen concentrator, it's just a nebulizer on oxygen flow above 2 liter per minute

Very easy to use can operate with a special car adaptor too

Although brands are generally intangible, we often associate things like products and names with brands.Oxygen flow is very nice

It does not work properly needs return my money back to my account

Bought this device for my father as a gift. He at times after his walk feels extremely tired but this device his really helped him recover fast.I tried it as well and it leaves the person feeling really light and refreshed. Our city lives leave us devoid of clean oxygen, this device really fills that gap!
