extremely quiet This CPAP is extremely quiet and I think I am sleeping better. The only reason it didn't get 5 stars is that there is no option to use it without the humidifier. I turned the heater off and use it with the humidifier empty, but other models have the option of simply closing off the humidifier area and making the machine smaller. I do prefer the Auto Pap.

The unit shipped was defective The unit shipped was defective, but after having emailed them a copy of the unusual sound they device made, they were quick to respond and send a shipping label to send the unit back. Even though I don't have a unit, they interaction leaves me very satisfied that I will go back to them for future CPAP need.

Despite Webpage Problems, good Customer Service Due to a problem with the webpage, I was unable to log into my account to place an order. After numerous attempts to change password and confirm email there was no success. I did chat with a representative and ended up checking out as a guest, and it finally allowed me through the process. Once order was complete, item was shipped and I recieved about a week later via USPS priority.

Great Customer Service I ordered a CPAP machine for my husband to leave at my mother's house so he would not have to transport his every time we spend the night. Steven answered all our questions via chat on the website. After we accidently ordered two units we quickly reached out to Steven again who sorted out our problem the same day. A day later our unit arrived ahead of schedule and in perfect condition. I highly recommend using SistemmaCPAP for all your CPAP supply needs.

pleased So far, I'm highly satisfied with my ResMed ASV machine purchase from Sistemma's website -- thanks! the order process made it easy to provide a copy of my prescription, and the shipping method got my machine delivered within a few days of shipping. Well done!
