It was recommended to me by lots of guys here and elsewhere to get the Eheim. I did works fine, nice and quiet and solid too.
But regardless, the Eheim can fail as well, $@*t happens.
I use MBM in conjunction with "Shutdown Now". I have the high CPU temp alarm set at 43C.
Just for the heck of it I unplugged my water pump and it took 1 minute for the temp to rise from 33c to 44c and begin the shutdown process. Quicker than I expected!
I think the program was well worth the $30.00. Just the time savings alone of having to take it all apart and replace the chip is well worth the cost.
Now all I need is a leak detection shutdown program!
