Aesthetic, practical, compact ... soon tried soon adopted by all! we fought for decision, it clings to the charger all! With 5 ports can be connected to phone, tablets, cameras (or battery charger for EOS eg), Nintendo DS children (with a universal cable compatible with car chargers) ... Plus: there is a link "scratch" to attach the own charger cable which avoids having cable lengths on desks.
It is useful at home, on vacation, of course, but also at work where one still chasing an extra USB port. In short try it and adopt it, but now he'll have to watch!
