The plastic smell inside that NeilMed squeeze bottle is awful. And it scares me a little. I think I washed mine 5-6 times and let it sit open for two weeks before I used it.

I think there are pros and cons to each method - the main thing that bothers me with a traditional neti pot is that it sometimes drives infected goop into my middle ears. Not good. The squeeze bottle doesn't have that problem - but doesn't do as good a job cleaning either.
