Klein - virtually - and uncertain

I also bought two years ago as a stick, primarily because I could leave the plug in my netbook. So I had always with a medium to exchange data and the key file for KeePass could it also. Peeling and the netbook was uncrackable.
so far so good. Was bad that the first was broken after a week - well, may, that's what guarantee. The Keyfile can not start something anyway. So exchanged.
Then it was time well and now again, is recognized as a USB device, but can not be opened. That was after I repeatedly off the stick and plugged had (logged)!
Following a tip from a similarly injured I have bent to plug and actually, there is a Micro-SD card in it then also in an adapter still worked well.
It seems to me that the main problem (which, incidentally, in this form in almost all Micro - USB sticks occurs) because of the fact that the card are connected only by very thin and long spring contacts with the controller. Since contact problems are inevitable, either due to corrosion, temperature or impact.
If we examine the customer reviews of various sticks (one needs only to look at the 1 star - always the same problem) there are obviously better and worse.
This definitely is one of the worse.
