I found staff very knowledgeable about their products and answered all of my questions. I received my cpap machine quickly, compared to waiting for NHS, which actually would have never have happened! My doctors actually changed their mind about referring me to the sleep clinic as they didn't see me as a priority. thanks goodness this company exists and I was so disappointed and very tired! I just want anyone reading who is new to cpap wearing and struggling to know it took me a good year to get use to my mask. don't listen to your negative thoughts to much is my best advice. Each night now I pop it on and don't over think and fall straight to sleep so bear with it.
