Previously I had purchased another organizer but realized it was a little too small for all my needs. It was sufficient for external HDDs and some cables but not all my accessories. This product has plenty more room. The organisation is excellent with several pockets for almost everything. There's even a spot for an SD card on it's own which is slightly hidden in a larger pocket. It's not too big and can easily be slid into a rear pocket of a backpack. The size is about the same as an A4 piece of paper. The zips seem sturdy enough. Definitely happy with my purchase.
