My wife is terminally ill and is on oxygen 4 ltr /hour permanently and with the cannula up her nose 24 hrs a day I was pleased to find nasal masks which I ordered with Elley Perfect on Monday 24th April 17 and to my surprised received them the next day Tuesday 25th. (5 Stars) Unfortunately they were too big for my wifes small face and spoke to another girl in absence of Elley Perfect on the same day of delivery who stated that only adult size or children's was available and said that she would post a childs mask straight away as I stated circumstance. Sadly yesterday I had to put my wife in a hospice still with sore nose apart from all other problems and still have not received said childs mask. Hence 3 stars. If it was posted 1st class as promised show this to your postal company concerned
