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.

Outstanding value The price and availability were outstanding - 5*'s Three complaints in the online reviews are not issues for me. 1) Hose extends straight out the back and won't allow the unit to be placed against a wall. This is a non issue since the hose has a small bend radius and doesn't extend much further than the Airsense 10 with the 90° elbow. 2) Unit has AutoStart and no AutoStop. The Airsense 11 has both but clinician has to configure the AutoStop. 3) Water chamber is too small and runs out of water. I used the Airsense 11 for 8 hours last night at the highest humidity setting and still had water remaining this morning. I would have given the purchase a 5 star rating except for 2 items. It took 10 days for the shipment to arrive. Might be out of your control and is a UPS issue instead. I submitted the prescription for the purchase and setup. I expected the unit to be setup per the prescription and ready to use. Since I am technically savvy, I was able to configure the unit and use it this weekend. I will contact the doctor on Monday to verify the settings.

HAPPY HAPPY ECSTATIC CUSTOMER I was notified the CPAP Machine I was interested in was back in stock on a Friday. I then placed my order via SistemmaCPAP.com the next day and it arrived by USPS Priority Mail on Thursday. Along the way Stephen contacted me to ensure I had everything I needed and he was responsive to a request for my insurance pre-certification. Excellent customer experience that I wish was the standard today.

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.
