Extremely fast stick with dubious mechanics

I do the basic tenor of the positive reviews here only agree: The stick is fast - very fast. The values ​​specified by the manufacturer for sequential read and write speeds are significantly exceeded my 64GB copy with 207/105 MB / s. This I had basically never expected - already not a quite reasonable price.
The trouble is that the mechanical quality of the SanDisk drives less trustworthy fails. The slider feels very cheap and it's probably only a matter of time before a fault occurs. Too bad that it is essential to save here - the small extra charge for a solid solution would certainly have prevented anyone from buying.
