El-my hubby and myself both use one.
They take a little getting used to(the sensation, head position, etc.) but I feel so much better after using it-so it is worth the practice
It is great for sinus issues related to allergies, infections, and colds.
Make sure to use warm water-it will help to alleviate that(water up your nose feeling) and warm water helps to break down the mucous easier.
The saline packets are nice, no thoughts on how much salt to add, but we just use kosher salt.
Good luck, I hope it helps
