IMO, for something as critical as your return pump, stay away from the cheaper DC pump brands (ie. Jebao). I know tons of people have used them without a hitch... But, last year, I had one in my tank for about 7 months. Worked flawlessly. Went on vacation, pump seized the second night I was away for no apparent reason. Had to call my LFS emergency line to get it replaced with a Mag drive.
I have the M1. I was very skeptical of buying it because of the price. I'm telling you, it is worth every penny. Super controllable and it doesn't make a peep. No vibrations, nothing. It's awesome.
