    Great!

    Positives:
    - Impeccable finish.
    - Flexible mounting (three choices, easy to fit; clip on, clip off).
    - Extremely quiet on medium and high (more than enough).
    - Moves an impressive volume of air.
    - The sheathed cable is very elegant too.

    Negative points:
    - Not cheap. Cheaper models might do the job, but if you can stretch your fan budget a bit, it's worth it.
    - You can hear it very well in ultra high mode, but in my case, there's no point in pushing it that hard.

    In short, if you want the best in fans, go for it, but don't forget that earlier models can also do the job perfectly well. The fact that you have three choices of mounting is nice, but if you know exactly what you want in terms of mounting, is it really worth it? It's up to you to decide!

    Super

    Fits neatly into a Fractal Design Pop enclosure, silent, adjustable by PWM over three different ranges.
    Complete mounting kit (choice of conventional or anti-vibration screws). Really top-notch.

    Perfect

    Powerful and quiet. Three stand sizes supplied (small, medium and large) and rubber cleat to absorb vibrations. Durability remains to be seen.
    Worth the price.
