The Waterpik SinuSense Squeeze Bottle is a more modern/unique design of a Neti Pot. If you don't know what a Neti Pot is, it's basically meant to completely rinse our your nasal passages with a saline solution. Most Neti Pots are a pain to use because they are basically a tea pot, and can spill and drip every where. The SinuSense Squeeze bottle is made to fit perfectly up your nose, so you don't have to worry about dripping and you can control how much water flows in your nose at a time. The great thing is that you can use the SinuSenze Squeeze bottle twice a day everyday, so if you are constantly congested this will get rid of it completely. It comes with 60 saline packets so you can rinse your nose twice a day for 30 days, and then just buy more saline packets. If you've read my reviews you already know how fond I am of neti pots and rising out my sinuses. This SinuSense was no different. It was just a different design but had the same effect. Like I've said before when you use a nasal rinse you can see all of the mucus coming out of your nose as you are rinsing. Even more mucus comes out when you blow your nose. I find it completely gets rid of all nasal congestion, whether its congestion from allergies, sinus infections, or colds. I find that it also helps my duration of colds and sinus infections to be shorter. I've also found that I don't get sinus infections as often or if at all if I use the sinus rinse. I would truly recommend to pick up some sort of neti pot if you don't already own one. I own several different designs and this one is my favorite. Effectiveness Most effective product at getting rid of excess mucus, and helping with sinus infection or colds. I can't recommend this enough. I would use this with a cold medicine, and it helps me get over any sickness in no time. Not only that but it does a great job at cleaning out my nose. I love it Ease of Use It's very easy to use, and much easier then a regular neti pot. With the squeeze bottle you just put the water in, then the saline solution in, put the top back on, shake the bottle, stick it up your nose, and rinse. Just follow the directions and you will have no problem. I got it on my first try. Immediacy Just like a regular Neti Pot you can feel the results immediately. The nasal rinse along with the saline completely gets rid of all congested mucus stuck in my nose and sinus passages. I can breathe clearly and freely after using this.
