I bought it and it sounds like a vacuum cleaner, but moves good air. Not at all worth it though. It's 12v too but 5A...it was such a bitch to find a 12v convertor that can handle 5A.
The one on my boat is loud as hell. I also think they would wear out quick. I don't think they are designed for continuous use. You run them 5 min before firing up your boat engine and that's it.
