I had been using a ResMed F20 full face mask for six months. It was comfortable enough, but leakage and events were high. I was averaging 10 - 20 events per hour, and not sleeping well. I decided to try a nasal mask, the Resmed N20. After settling on Med size, I saw immediate improvement. Leakage was nil, and events went to near zero, averaging 1.5/hour, and sleeping like a baby.
Respshop has been great. The web site is easy to navigate and choose the parts I need. Shipment has been prompt, sometimes within a few hours. All product I have ordered has been received sealed in ResMed packaging, not repackaged, unlike some other companies I will not name.
The first time I ordered from RespShop, I ordered the wrong items. They would not take a return, because I had opened the packages before I noticed it was the wrong thing, but did give me full store credit.
