After a first copy of the sticks had left me in his first serious use in the lurch, the second drive is now running as it should. The exchange at Amazon went off without a hitch - complained shortage and the old hardware returned. 2 days after the complaint came already the New. Normally I test USB storage before first use, this time I had unfortunately failed (indeed needs are pretty up the 16GB tested long) and I was able to pick up the much-needed data again. The 16GB large storage with USB 2.0 port hangs with me on a keychain and therefore must mechanically withstand a lot. The print is indeed already almost impossible to read, but the mechanical drive is very stable. Through the sliding mechanism of the connection is very well protected. Dust and dirt but can still advance to the contacts because the slide mechanism connecting only feeding, but the contacts are not covered. Not then, but also to the price - With regard to the speed, the stick is considered good midfield, but there is also much faster copies. In the evaluation, I have made a write-down of a star for the first defective copy, the second star is missing because of the missing dust cover when closed.
In such an "Always with Stick" either include absolutely no worth protecting / or personal data you need to be encrypted! For the latter, Truecrypt is excellent, since it does not have to be installed in the portable version (and therefore can be run directly from the stick) and is available for many operating systems.
