@laureltn, I bought it on Amazon.de about 2 weeks ago. They definitely shipped it to the U.S. via DHL. Ordered it on a Monday, received it on Thursday that week. It was very powerful with 3% saline and very good with 5% saline. The frist time I nebbed 7% saline, it worked very well. The following sessions at 7% saline were weakening a little bit each time. After 4 of those sessions, it is definitely weak. I contacted Pari Germany, we'll see what they have to say. I have until Monday to return it to Amazon.de.
I wonder if the 7% saline is too heavy for the mesk. I use PulmoSal, there is sometng in it on top of the 7% saline, baking soda or something else. Maybe that clogged the mesh, not sure. I have been carefully cleaning and sterilizing after each use (twice a day), ran maintenance care sessions whenever the blue light was on (every 2-3 days). I know I have been doing everything I was supposed to do. Maybe the regular 7% saline would have worked better, or maybe not.
When it was working well, I was very impressed by it. It was very powerful, very fast, it was the very best nebulizer I had ever used. I hope you have better luck with yours.
Best wishes of great health to all of us!
