Does anyone here have any experience of buying portable oxygen concentrator ?
I checked the price for Philips easy go mini a few days ago and it costs a whooping 3000 US dollars, Oxygenmaster listed out the price quotation as RM 15,500. Any cheaper and reliable alternatives ?

When I searched the item on lazada, it listed some of the devices ranging from rm1000- rm5000. Any feedback on the reliability of the machine is very appreciated .

Thank you
