There hasn't been much innovation in power heads for years. Its about time someone challenged the two main players with something new, at a very reasonable price. Its exciting in what was otherwise a stagnant market.
I always hear about all these marketing costs, but how many tunze or ecotech commercials do you see? I've been reefing for years, yet I wouldn't even know where to even find a marketing piece from either company, nor care.
You will get better warranty service for sure, but when a wet side replacement costs as much as one of these pumps, does it matter? If these pumps die quickly, then yes it will, but if they last....
If these pumps remain solid and don't fail quickly, they will start becoming widespread just like the good Chinese LEDs. The popularity of these pumps and the Chinese LEDs only exist because of the absurd pricing of the other players in the market. They are filling a void which has been there for quite awhile, and it was only a matter of time before someone seized the opportunity.
