Great machine and works flawless filling up my CPAP daily. Takes the chore out of filling it up myself nightly and will keep water level at all times so won’t run out by morning. I recommend getting the extended tubes too place it on floor area as I also bought the tray it sits on and highly recommend that as well.

Resmed 11 water chamber

Working perfectly 🥰

Seals just as well as the original.

I believe this is actually made by ResMed so it's not surprising that the seal is basically perfect.

The placement of the stickers (sensor holders) is not always consistent... I imagine that CSpring is the one putting on the stickers.
As long as you pay attention and put them where you need them, each time you get a new one... You'll be fine.

After years of dealing with Resmed's tiny water chamber, finally a great solution

I am so thankful for this product. My sleep is no longer interrupted from a dry chamber and being woken up in the night. Ive suffered for years with this problem. Ive complained to Resmed to no avail. Ive looked for alternative cpap machines but they all restrict the size of the water chamber. Cspring solution is great.
I did have any set up issues at all. It worked perfectly first time out of the box. Ive told my docs at Chicago ENT sleep center about this product. This isnt a 5 star product but a 10 star product for this issue.

it works great. Not having to fill up the water for about two weeks. Customer service is fantastic. Good product.
