I've issues with a dodgy zip on this bag, and this is on the 2nd bag I got...... The first one was replaced because the changing mat cracked and tore where the horizontal & vertical bends met. This made sharp bits of the plastic covering stand up, which isn't good for baby's soft skin. Also, because of the tears, any accidents result in urine seeping down through the tears to underneath the plastic covering. Never to be gotten out again......
My 1st bag was replaced because of these changing mat issues, but the changing mat in the 2nd bag has also cracked and torn in the same places. I just can't be bothered sending the whole thing back again.
