When tasted this kind of product, we can not do without! This USB key-shaped drive is a thousand times more convenient than the usual camera-PC connection cable to download photos. The cable, it takes up space in the bottom of the bag, it twists; suddenly, it does not trump every other time ... and we always regret, obviously. Small, discreet and very light, the subject is forgotten in a pocket of the bag until we need him. Just then slip the memory card, and go! Self-powered by the USB port, it works by reading and writing; suddenly, I use it sometimes to the household on the map. In brief, a really great accessory. I am always surprised that it is so hard to find in commerce ... This model from LogiLink is not a very robust design (less so than my first reader, Lexar offered with an SD-HC card): caps are a little loose, for example. But it serves its purpose perfectly for a ridiculous price.
