We got these in yesterday. I hooked up a #3. There are definitely pros & cons when you compare them to the nano streams. Pros are prop pump flow with minimal cost, and are probably going to be in much better supply than the tunzes. Cons are that they are definitely lesser quality materials, and if you read the warranty fine print just about everything that happens in a reef tank is going to void the warranty. Also the magnets aren't nearly as strong, and the pumps take up more physical size in the aquarium. The #3 is 850 gph and 10 watts, where the nano 6045 is 7 watts and 1150 gph.. so they aren't quite as powerful as well. I"m sure they are going to sell extremely well, and people who buy them will certainly have good results in their aquariums. If availability was equal, I think I would stick with tunze in my personal tanks, but can't fault anyone who chooses the koralias.
