This arrived yesterday and I was so excited...but it is just too small for my stuff.  I commute to work and carry quite a bit of stuff and the magnets don't hold when I have it filled.  My experience is if there's not enough room when I load it it won't work as I accummulate stuff!! and am horrible about cleaning out my bag.  I am returning it but love the style so will probably go with either the diaper bag (love all the pockets) and pitch the changing pad or the gym bag.
