They work well
These work well. A couple of things would make it five star -<br />First, and most importantly, put some instructions somewhere!<br />Although these might seem obvious, they really aren't, especially if you have never done a sinus rinse before.<br />Second, the flow is a little weak. That, in itself, isn't so bad. I'm just used to a stronger flow. I don't know how to fix that.<br />The plusses - they are well-designed, washable, easy to fill. The markings on the side are helpful, but would be even more helpful if you would at least tell us what the units of measurement are. I assumed that they were ml. and I think I am right. I'm an American. What do I know of metric??<br />Anyway, overall, I like them and glad I got them.
