Fantastic improvement. 
After using ResMed fx swift nasal pillows daily for over 5 years, I got tired of the periodic episodes of irritation and uncontrollable, continuous runny nose so I ordered this mask and harness. 
I am extremely delighted with its amazing comfort and flexibility. It stays in place, is very very light weight, makes virtually no noise and doesn't leak cold air! I ordered the women's small and it fits my not very small nose perfectly.
