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.

Reliable source for supplies We are regular customers. They have a reliable inventory and provide quick and friendly service. Twice they have called to make sure shipping arrangements were right when usps couldn’t find the address in the system. Extra steps like that give us peace about having a long term reliable supplier for replacement parts.

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!

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.

Thank you SistemmaCPAP I had a great experience with this business. Most up to date machines in stock at lowest advertised price. Service was prompt and professional, and machine showed up fast despite opting for free shipping option. Couldn’t ask for a better experience.
