Mine are not a year old yet but running well. I do find the wiring connection running into the bottom of the controller to be kind of not well done. Seems easy to pull the rubber insert around the wires out of the box. I have mine electrical taped tight to the box just in case.

I have two MP40W which I've upgraded with the new ES drivers. One of the pumps is over two years old and was a Gen 1 when I purchased it new. A few months after the purchase, the Gen 2 improvements arrived on the scene and I upgraded the magnet, driveshaft, bearing with the kit available from EcoTech for just over $10 if I remember correctly. About a year later I got a deal on another forum for a NIB MP40W that had become surplus due to a change of plans of the hobbiest selling it. So I got a decent deal on that one.

Other than replacing the Gen 1 parts, I sent the original pump in just before the warranty ran out since the dry side seemed to be making a somewhat unusual sound. The pump was still working fine, I was concerned about the sound, made a recording and emailed the sound file to EcoTech. They suggested I send it in for them to have a look see, so I did. Returned relatively quickly with the problem rectified at no cost.

So other than the aforementioned blips the pumps have been working very well and I wouldn't trade them for any other mode of water movement, be it a competitor's pump or closed loop. Unlike some of the other posters, I rather neglect them with respect to cleaning. Brush the wet side components down with a toothbrush periodically, but have never soaked the wet side in a vinegar solution to dissolve coralline buildup.

I do have one beef still though. Seems the night mode has a habit of kicking in later every evening. This was a known problem with the original wireless drivers when that option was added by a firmware upgrade. I really would have thought that EcoTech with their reputation of customer satisfaction and innovation would have solved this with the new EcoSmart drivers, especially after I decided spend the extra bucks to upgrade. I gather the solution is another firmware upgrade, but it seems to be taking quite a while to get that out to us, so I'm almost suspecting there's a hardware issue that can't be solved by a firmware fix. You'd really think with all the features, they'd have an accurate timer or clock inside the box.

I have 2. 1 for 8 months and the other for 2 months. Had problems with my older one twice bit the ecotech customer support was out of the world! had my new part within days. Other than that the pumps are great and I am very happy with and wont run anything else :)

have 2 MP40s the older one was still under warranty and was making lots of noise I emailed the rep and he set up a new wet side for me no questions no charge now its working great - the other MP40 a new version had no problems from the start -I was told some of the older MP40s had a bearing problem on the wet side and thats what they felt was the issue with mine. Love em great flow. $1000 worth of power heads I expect nothing less

i have 2 mp 10s. they are less than 1 yr old and they are so noisy that i have to return both for service. hmmm. dont think i will purchase any more :(
