I own this stick now for over 2 months. With regard to reading and writing speeds was here already reported a lot. These are sufficient for me definitely. But what I like Berchten relates to processing. If you look at the pictures affects the stick very high, but if you then hold it in your hand you realize that it is made of rather thin plastic. He works like a pen - if you with your thumb on one end presses coming down the USB connector out and snaps, pressing again he drives by itself again. Although this is very convenient, but looks a bit shaky, so a star deduction. Overall, I've been buying and also the slightly higher price no regrets and would highly recommend this product.
