I do rinse it with tap water to get the salt out each time. After using this for about 6 months, I still needed sinus surgery. I believe that the real value of this machine is one, consistant flow of water through the sinus area. Two, it delivers 16 ounces of water versus 8 ounces for just about everything else on the market. I don't know that the pulses do anything. I would buy this again and I would normally rate this a 4 start, but I give it a 2 star as a caution to those hoping it will cure you. It won't. Answer:

Review: I don't like Tool but I thought that since "Judith" wasn't as hard or aggressive as the songs you would hear on a tool album, I had high hopes for A Perfect Circle, especially since Trent Reznor had invited them to open for NIN on his tour. When I finally bought the album, I was sadly disappointed. With only 2 good songs on this album outside of Judith--those being "Rose" and "3 Libras"--all the rest of the album is rather average and sometimes just outright bad , especially the song "thinking of you." While I may not have liked Tool at least I had a measure of respect for them. I have no respect for A Perfect Circle Answer:

input:  Now, answer this question: Is this product review positive? Title: Poor Review: As a student, lessons are not explained. Having a poor teacher doesn't help, but every time I turn to the book an explanation is lacking. After reading the unit, the problems generally seem completely detached. I will work through the examples and come to an understanding of the material, and not be capable of completing a single exercise. Very difficult book to understand if you are not already fluent in mathematics. Coming from an otherwise A student. Answer:
