This Review Title is Not great and the content is: The pump itself sprays just fine.  The musty odor is a big problem.  I have tried dumping the water and letting the unit air out in between use but that does not work.  Now I must pump several times to flush the smell before I can spray my hair.  Not convenient and would not recomend..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
