I've been wearing these on and off for a good 6 weeks now. They are amazingly lightweight, and have a good 'barefoot' feel to them. Good breathability, so cool in the heat (I used them for runs while visiting southern Italy). However, the sole is not that rugged. The Vibram part is ok, but the grey part is much sorter and already wearing must more that it should do I think. If treated carefully and just used around town they might be ok, but an rougher terrain or road use will not suit them so well.
