TOP USB Stick, wobbly sliding mechanism

The USB stick is awesome in itself - sauschnell push data back and forth. Perfect.
But the sliding mechanism is somewhat questionable: if one "extended" the USB connector has and will kindle him, it happens all the time that something "rigid" USB ports, the plug simply sliding back and at worst, not a clean contact is made. I do not even happened that by a blue screen was triggered in Win7 - an error rarity! Otherwise, offered the perfect stick data exchange, ideally on a key chain.
Unfortunately, now is for some time but the little measly plastic tab, where the key ring passes, broken, probably fatigue. Too bad that could have been done in metal.
Therefore, "only" three stars out of five. Data Transfer 5 star, execution maximum 3 stars.
Conclusion: Top Stick, which you think through and could improve !!!
