l have been given a oxygen concentrator which is kept upstairs in the bedroom has any bought a Freestyle small contractor or similar to take out visiting people should l need it and have you any idea how much they cost. No price is given on the website and l know once you phone to ask they tend to pester to get a sale. Air Liquid said they are about £2000.00,
if someone has bought one are they very heavy to carry around they do give a weight I know but are they cumbersome. I have a portable one from Air Liquid but it would be nice to have one that is a bit disgrete.
