I had a Python for years, and somehow it went missing.
So I bought the Aqueon one. It works fine, but it's no Python in quality.
IMO, the Python moved more water when draining. I also never had the Python break, where as the Aqueon broke the valve on the gravel vac before I even got to use it. It was assembled too tight, and from what others posted, it's the same with theirs. Aqueon is replacing it under warranty, but it's still a pain.
