Over reviewers have reported that it's a tight fit in most USB ports, particularly in metal laptops like Apple MacBooks. Even with a plastic Dell Inspiron, I've found this to be a huge problem. It's hard to tell at which point the drive has bee inserted fully into the socket, and to remove it I have to wiggle it from side to side, probably damaging the innards of the USB port. I don't think I'm especially weak, as I open jam jars easily, and every other USB plug I've ever used has been much more conveniently slippery.
It's apparent that the metal edges are thicker than most USB plugs', and the usual two holes on one or both sides are missing - these are features of the design, but maybe I was a victim of a freak oddity in the manufacturing process. I would send it back if I still had the packaging - since it cost "only" £4, I suppose it's not the end of the word.
On the plus side, it does look and feel very nice, and it's compact enough that other things can be plugged into adjacent USB sockets at the same time. It's certainly sturdy, but my problem is that it's *too* sturdy.
