I love my MP-40's. It is a ton of fun being able to sit in front of my tank with my phone and adjust what they and the Radions are doing.
They replaced my before favorite of koralias. Though replaced in the tank, I still use them to make up my water for water changes. The downfall is how they will sometimes start up and go backwards...and when I had a ton of brown outs would be continually resetting them to work in the right direction. Would always send sand everywhere...hence why I wanted to replace them when the piece broke to start such behavior.
That being said, I'm hoping to see something new coming out of Ecotech in the next 6 months to a year. The drop in price on the MP-40 points me in that train of thought. With those gyre type powerheads that hit the market, it would make sense to see something like that out of them with their own touch, excellent customer service, and great quality of product.
