After such a card reader I had always been looking for. I photographed on a holiday tour with my PowerShot S95, pushed then the SD card in this card reader and transferred the images and movies on my smartphone, a grade 3. There I worked on it and sent them either by email, WhatsApp or Facebook. I give this product 4 out of 5 stars. As I wrote in the title, it is almost perfect, the only point which leads to the withdrawal of a star, the fact is that the caps become independent. Here a solution would be good in the caps would either not exist or would engage. The inventors are no limits.
