ResMed always has the best CPAP machines on the market and this is no exception. I've tried a few other brands and always come back to ResMed.
Frankly I'm not sure how the S9 Elite is different from the other S9's, but I'm a fan of the sleek look and the quiet, simple operation.

I've been using many different CPAP's for years and I haven't found a better machine. There are other brands that are good "starter" units,
but this is clearly the best. Sleep never felt so good!

Sleek and quiet. Has all the bells and whistles and doesn't wake my husband up. I've had other CPAP's from other manufacturers and they always seem
to end up vibrating or smelling over time. The guys at Activa really did a great job of walking me through the options.

Worth every penny. I was a little skeptical of buying the S9 because its higher priced than some of the other brands. After using it for about 3
months I can say its worth every penny. Quiet, small, doesn't dry my throat even without the humidifier because of the easy breath function. I love
it.
