Query: Returned it

I purchased this from my LFS for quite a bit more than what is shown here, so price wise, this is a good deal. But the priming is near impossible. It took forever for my son and I got get it to work the first time. I had this thing running just over a month, any power glitch and it would not restart. It wouldn't clean the tank, so I kept cleaning the filters and each time, I had to drain the pump halfway and 'open the floodgates' for it to start. when it started stopping without power interruption, that was the last stratw. My LFS took it back which I am thankful. I will never buy another Fluval anything again.
