I got home last night to find the "wet" side of my MP40W at the bottom of my tank. The impeller seems to have snapped. This is the second unit that has broken in 6 months. The first time it just wouldn't run after 1 week of owning it. Eco-Tech Marine replaced it, but it took 5 days, with a shipping screw-up on their part. Last night I attempted to go on their website, and it was down. It's starting to seem to me that these products are more hype than anything else. $429.95 should buy me a product that does not break twice in 6 months! I'd like to hear your thoughts, and any other bad experiences like mine out there.
