The first patch is supposed to be 400 of each for the US.
I am not annoyed, I enjoy helping people with honest questions. These pumps are not very expensive and my margin on the products is pretty slim, way below what is the norm for an importer/distributor. We work on 10-15%, the norm is 25%. If I didn't like what I was doing, i could certainly make more money doing something else. I just like my job and I like Tunze.
