I absolutely love Simply Saline. I have a deviated septum and get sinus infections almost every time I get a cold. I've been using Simply Saline for every cold I've had in the past 3 years, and I've not had one sinus infection, or even a rough, sore nose from blowing it too often. It clears out all the gunk so I can breath again, and keeps my sinuses healthy. A+!
