res-q-rinse
The most effective method of performing sinonasal irrigation yet invented by mankind; its amazingly simplistic and respectful design attributes help prevent the choking, coughing and aural fullness problems experienced by patients who have ultimately discontinued use of other nasal irrigation treatments.
I've got serious sinus problems and had several sinus operations; no other sinus rinse works as well as res-q-rinse to maintain my nasal health...and I've tried em all.
