As a lifelong allergy and sinus sufferer, I tried plenty of things. I had a neti pot yrs ago, but I didn't use it frequently enough because it didn't seem to work well enough for the mess of it. This new device takes all the mess. You put in clean salt water, insert the silicon tips into each nostril and press %26 hold the start button. The salt water is pushed into Nostril A and around the back of the nasal cavity and back out Nostril B. Turn the nostril tip applicator 180* and now water into Nostril B and out A. The refuse water collects in the bottom catch tank. If you aren't grossed out, you can see some “floaty” bits in the refuse water, which gives me the satisfaction of using it. The pressure can be a bit much to start, so the instruction manual explains how you can leave the top tank stopper slightly ajar to reduce pressure. I started on full and wasn't troubled by it. I'd recommend to anyone who is much like myself; I near daily stuffy or runny nose and some level of a sinus headache. I still take Allegra so it's not a miracle. Just part of my overall treatment.
