I used the Crossan tip with a Water Pic (Professional model) for over 4
years. It stopped working. I bought a new one, also a Professional
model. It lasted 2 months. Bought another one. It lasted two months. So
I bought a bulb type syringe and put the rubber tip from the Grossan tip
on the syringe. Using the reservoir from the Water Pic I mix 2 1/2
teaspoons of salt with 32 oz of water. I fill the 3 oz syringe with the
mixture and squirt it in the left nostril, fill again and squirt in
right nostril. I continue to alternate back and forth until all the
mixture is gone. I do this every morning. I feel that I am getting a lot
better cleaning using this method over the Water Pic method. To see what
the syringe looks like click on the URL below.
