You need to be able to make a seal between the nostril and the spout of the pot. I do know that people do use the bulb syringe method but, from what I've read, the pot is preferred over the bulb, from people who have used both. I took that info, and skipped the bulb, going straight to the pot. A friend who was using a bulb (she had had sinus surgery) went to the pot when she found out about it. I think it must be about the flow of the solution, maybe less hassle.
