Oxygen Concentrator for Home, Vogvigo 93% High Concentration Oxygen Generator Concentrator, Oxygen Machine 1-7L/min Adjustable, Oxygen Concentrator Machine Portable for Home Use, Remote Control

The instructions weren't the best but despite that it was relatively easy to set up correctly. It came with nose clips but not a face mask so order one if that's what you prefer. The remote is a nice touch but you have to have a clear line to the sensor. Provides decent oxygen, a little disappointed you can't lower the flow independently of the % but considering the price it is a decent machine and has helped keep my mother out of hospital.
