Well, first Seio is plagued by the Taam (same makers of Rio pumps) stamp of approval, but lets assume that doesn't matter. I think the biggest downfall for seio pumps is the very constant inability to restart after a power outage, or unplugging. Sure they might start up flawlessly, but I've had multiple 620 models, and 1 of the 1100, 1500 & 2600 models and just about everyone of them have had issues with restarting, sometimes they restart no problem, but occasionally they will chatter chatter and freeze, and this is something that many people have observed.
Besides that, the Seios really aren't made to be mounted effectively, they come with that 90° bend that shoots outward, but as most have found that's a really inefficient way to use them, so you yank the shroud make them look more like a conventional powerhead, but then how you mount them can become troublesome. But again lets say that you are lucky and have a tank that manages to fit them nicely.
Don't get me wrong Phong, if you have them use them, however for a inexpensive alternative I would probably recommend a Koralia or Modded Maxijet over a Seio, I happen to use them on my softie tank because I have them, but I wouldn't buy another. I am in no way saying you NEED a Tunze or Vortech type pump, but I am saying there are definitely nicer "inexpensive" pumps than the Seio pumps.
