After about 2 months it needed cleaning because the flow was reduce. I took it out and soaked it in 50-50 vinegar water like they recommended for 5 hours and the plastic warped a bit and the Gyre started making a lot of noise after that. It was also a pain to put back together, the A and B cages are marked by tiny little letters that I needed a magnifying glass to find.
I went back to my mp40 which I go up to 6 months without cleaning.
I see a lot of people bashing the Jebao "gyre" as cheap chinese knock-off. Well the Maxspect Gyre feels like chinese knockoff to me. When I open a Vortech pump or a Vertex skimmer, it feels like a well-made product, not the Maxspect Gyre...
