I bought this for my dad so he could transfer photos from the PC to a digital photo frame. Though the frame has slots for all types of photo cards, using a faster USB stick was preferable and less faff at the PC end. However, a typical USB flash drive would be so big as to stick out and be visible hanging off the side of the photo frame, so I looked for the smallest one available. I was still surprised when it arrived at just how tiny this thing is, and it ensures that it just stays out of sight.
One thing I was pleased to see is that on the back of the packet there is explicit reference to 'Linux 2.4.0 or higher' amongst the supported operating systems. There is no reason why the vast majority of USB flash drives would not work on Linux out-of-the-box, but it's good to see the manufacturer has bothered to list it anyway for buyers' peace of mind.
So far it seems to work fine, but requires insertion upside down on the PC USB port. There is a short cable supplied that can be looped around the hole on the drive for attaching to a key ring or hanging up somewhere to avoid losing it. Other brightly coloured versions of this product are available for those who fear it will slip into the nearest dog, but this one is good if you want something more discreet. There is also some small EXE file for password protection software pre-installed but that is probably Windows-only and not required in my case anyway. It can be safely ignored.
