1. Could use some work in the instructions
It was all pretty simple to understand, with the exception of a couple of the instructions. One referenced a locking device which I could not locate. There were a couple of these instances, but looking at all the other languages, I'm assuming the manufacturer's writers might have been a little weak in the English language.
As for the equipment itself, I'm still trying to get a steady stream of fluid to flow (as the instructions say).
