In my career as a PC-Freak with studying computer science I have already bought some sticks. Never have even remotely fit the specifications of the manufacturer. In this stick I was really surprised. The writing and reading speed makes just joy, because I hate it when I have to wait forever when copying data. In all my other 11 USB sticks is the case. When copying many small files while are, it usually takes several minutes. Not so with the stick of SanDisk. In just 20 seconds to store the amount of data, which I previously had to wait for about 4 minutes with other (also not cheap sticks). - Look - Personally, I like it very well. It looks very classy and at the same time very elegant. The build quality is OK. When pulling out of a tight-fitting slot pressing automatically on the flat sides of the sticks, respectively on the sliding mechanism, since it has the side pull no right to attack areas, (Very smooth and rounded). Here then I have always been afraid to damage the mechanism. The sliding mechanism works from home is not very stable, which is also of an umpteenth criticism from my perspective. So far, however, he has all the "pull-out actions" survived and is still working properly. How long the sliding mechanism for really hold out remains to be seen. Nothing is as it seems. Perhaps the impression is deceptive from the fragile sliding mechanism and at the end this is just as strong as the power of the stick when copying and storing data?!?! The bottom line, however, I forgive my full purchase recommendation for this USB flash drive from SanDisk !! The price here is for once appropriate!
