Ali Express is cheap Asian knockoffs, very well known in the $$$ high-end RC/DRONE world. Doesn't mean it won't function fine, and on something as simple as the beer gun will be nearly identical in appearance. If it helps your budget go for it, not trying to wave a flag here. I choose to support the developers of intellectual property and not the probable criminals stealing it. Whoever is behind it is not going to dedicate R&D dollars to coming up with the next great innovation in bottling from a keg, they will wait for someone like Blichmann to do it and then copy at 50-75% of the materials cost and 10-20% of the labor cost. No, I do not think Blichmann invented the concept of a counter pressure filler this is just an example, but they did make a pretty cool design for it. I like mine and want them to continue to innovate. Peace all, just my feelings on the matter after seeing companies like HPI and Losi obliterate their once flush R&D budgets under the same circumstances.
