It does work even if you're really stuffed at least based on my experience. I got mine when I was really stuffed up with a sinus infection that wouldn't budge. My Neti Pot wasn't doing anything but the Hydro-Pulse puts the water under force and it goes right on through. The device is a bit pricey. I paid about $117 with shipping and handling. If you could find one locally, you could save shipping. Also, if a doctor prescribed it for you, your insurance might pay for it. As I said in the article, it's expensive so it's really only worth it for someone who has tried everything else. You also could try using a washed-out dish detergent bottle. Sometimes people get a little more force because you can squeeze the saline water out rather than just pour it out. It's worth a try before you invest more money. Hope that helps. Let me know how you do.
