This Review Title is Some didn't work and the content is: 2 of the 4 spray heads don't spray any liquid at all. They pump properly, but nothing sprays out even after multiple attempts. The other 2 needed a few pumps to prime and begin spraying (not unexpected).  They are a nice quality, but useless if they don't work..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.
