I got the best deal! I answered a long survey about asthma and got an amazon voucher for £30. I spent £22 of it on an oxymeter. x

That's an excellent price Peter and Asda stores are reasonably accessible x

Can I ask do you always keep a check on your oxygen levels with an oxymetre or is a peak flow wot sit ok to be using?
