It was difficult assembly. It was secure but the leakage was 40. The highest I have ever had. I am not satisfied and sorry I tried it. I will use my old mask until I get a new a new nasal mask., I have bought many masks over the 5 years but not hppy with this one.
Received my new machine in excellent condition communication and service is awesome will definitely order all my supplys and furure machines from CPAP supply
very comfortable and fit well
When I wanted a second machine, one for the RV, I naturally chose this machine because I have had the one in the house for several years and it works well for me.
