A little tight at first
These straps were a little tight at first.  The first 3 or 4 nights I felt like the nasal pillows were being rammed up my nose and there was some discomfort.  It's ok now and I still like them better than the ones that come with the Airfit P10 as those loose their elasticity so quickly that the nasal pillows start losing their seal within a month.  However, I'll remember to stretch the next one out on a soccer ball for a few days before using it.
