Works as expected but bright

I love the convenience but the unit gives off a glow that is much too bright. I like to sleep in darkness and it is way too bright.

Hello Ms. Stanley, you can turn off the ambient lights simply by tapping on the power switch a second time.


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.
