Have this stick after a colleague bought very good experience with it and I made it myself had in his hand. The Transmission rate when writing, as always, depends on the number and then of course the size of individual files. When transferring small files from a symbol library folder (technical drawing, about 800 MB) I came to approximately 6.8 MB / s while a large single file with about 9 MB / s written to the stick. The stick is very shallow, short and easy. He has a metal case and a transparent rubber coating one can deduct from the housing. Etc. The fastening eye for lanyard But plastic makes a stable impression. Under this transparent eye and the activity LED sits the permanently lit depending on the status or flashes. These orange-colored LED is very bright and could, if one operates the stick, for example in the car next to a radio, night be very annoying especially. In this case you should choose a different model with a small, discreet lighting. For all other of the stick is especially at this price is a strong buy recommendation!
