Summary: For 16gb, this is very affordable. Fits perfectly in the little pocket in your jeans. It has a flashing blue light whenever it's connected, which is cool. Also, it comes with a 5gb free trial of Sugar Sync.
Excerpt: It gets the job done but, it has no cover for it nor does it have any way to carry it around safely. The plug in end of it is always exposed. It's a valued for its price! If you need an inexpensive way to backup files or move a large file from one machine to another, this is a great option. I also like the LED that lets you know if its reading or writing to it.
Summary: Pros: Fast shipping (just got mines today, saturday, even though it says that it will be delivered on monday). Good spare usb flash drive. transfer speed is ok (just transfered 2.8 gigs from it and took it 8 min to complete). playing videos is good. Cons: It is Flimsy (I should have listened to the majority of the reviews rather listening to one that claims that it is "not flimsy").
Summary: I got the pink one from a local store, and I've used it since Summer 2011. No problems of cracks or "flimsiness" as the other customers stated. Maybe this is made of higher quality, but I doubt it - they're of the same model and price. Today, as I was doing a laundry rush, I forgot to check the pants of my jeans, and this USB went in along with the washer.
Summary: I can't yet speak to the reliability of this device since I've only owned it for an hour. What I can say is that you need to be extremely careful when handling it. Sony made the interesting decision of making the outer edge of the USB connector out of plastic. Yes, that's correct, the outer shell of the CONNECTOR is plastic. Imagine for a moment how thin a piece of plastic needs to be to slide into a USB port.
