Don't have Radions, but bought into the MP40 pump technology early in the game, April '08. There were certainly issues with the original design (rusting magnet on wet side) original non ecosmart driver. For a very brief time I wondered if the cost was worth it. Support was exemplary though & they took steps to redesign the magnet as well as the driver to what we have today. Was able to retrofit new magnet & upgrade to latest driver at relatively low cost. That first pump has now been running for nearly 6 years 24/7 with no issues. Have replaced a few moving parts (shaft, bearing, propeller) on the wet side, but that's to be expected as normal wear & tear. Still a costly item, although price is down these days with competition from other products. For me there's still nothing like them out there, especially when running multiple pumps. Much more of a grey area when trying to get support for some of the competitor's products. EcoTech really stands behind their product.
