This model has been available since 2011 and I have been using one since then. It runs fast, though a bit noisy at full speed, it is a real workhorse as it runs for almost 18-20 hrs in the room where we installed it. It looks great as well. May not be great in terms of power consumption which is a bit on the higher end at 80 Watts but cant complain about the air delivery. It worked well for over 4 years after which it failed but it could be fixed by the local electrician and has been working fine since then. So all in all an excellent product which I recommend to all...a fan lasting 5+ years and still going strong...what else could you ask for.
