Yes, Sincerely has been a great help! So lucky to have someone step up to offer so much help!
I thought the eco 1 was way too loud and vibratey, but I am trying to stay really stealth over here, so it might not be as big a deal to you... but the thing vibrated so much that even when I HUNG it from bungee cords, I could feel the vibration in the wall the cord was hooked on pretty damn strong... wasn't sure where I could put it that wouldn't cause me trouble so I just returned it and bought myself another petsmart pump, but this time I got the strongest one... total strength is only about a third of the eco 1, but it is doing the job effectively, I've gotten good results bubbling with it! I left my old one in too, just to reinforce it, and between the two it's been treating me right. And it's just as quiet as the really weak pump I already bought, so it's perfect for my needs in that sense.
