Anyone heard of Manrose Mixed Flow fans?

http://www.greenspirit-hydroponics.com/mixed-flow-fans So I'm in the process of designing my first grow setup, and looking for a fan suitable for use with a cool tube and 400W HPS. I was going to go with the Ruck 125A, as it seems highly regarded among growers, but then I came across this. The low price makes me skeptical, as does the fact that I've not seen anyone on here (or other forums) mention it, but on paper this thing is quieter, consumes less power, and even transfers more air (on its highest setting) than the Ruck. It's rated for 30000 hours and comes with a three year warranty. Has anyone come across Manrose before? Thoughts?
