I have one of the RP-Ms. I may have just got a dud but mine is incredibly loud. Sounds like the prop binds up or scrapes against something. If I try to put it in reverse mode it screams a noise like it’s about to blow up. Currently it’s sitting in my tank but not plugged in. The did send me a new prop but it didn’t really make a difference. I just called it a loss at that point. I may use it for a QT at some point.
I am a big fan of the Coral box QP16 though. It’s a lot bigger but moves a ton of water silently.
