It’s not a problem I personally have, but I guess there could be forgetful people out there who can’t remember what’s on their USB memory stick. For those people one of the less-common models which sport LCD displays might be handy, and now TRUS is aiming their latest product at the sub-section of that sub-section that insists on being environmentally friendly. Their latest memory stick has both a display and a solar panel to power it.
Frankly there’s not much else to say about it; transparent shell, handy loop for attaching to your keys or nose ring, convenient end-cap to stop cat faeces from getting lodged into the USB plug. Let’s face it, you’ll know if you need/want this.
