In looking for a Neti Pot for travel (mine is ceramic), I came across
ads for the Nasaline irrigator developed by ENT doctors in Sweden.

It is a 2 oz syringe with a specially made nose piece that allows you
to inject saline solution into the nose. Apparently, one of the
advantages is that one can control the water flow and adjust the
pressure to the conditions of one's nose and sinuses.

Has anyone had experience with this device, positive or negative?

Is there any research on it?

Do you know of a down side?

Thanks for your help.
