I've had it a day and so far it seems great. It fits a NEX-3 with a 16mm pancake lens perfectly, I assume that a NEX-5 will be slightly loose in there. The zip and strap are perfect for the job and the case seems padded enough to survive a small bash or poke, although I haven't had the chance to drop it off a bridge just yet to test it.
Overall I'd say it's worth a buy if you plan to take your camera out for a dinner party or wedding and can't see it necessary to take a full size case. But don't expect to fit a larger lens in there, or any other extras.
