When the card reader arrived, it looked like it was too small for a usb fitting, but I was wrong.
What you get is a sleek well designed reader which snugly fits into the side of my netbook, without protruding too far from the outer shell.
It pushes gently and firmly into the usb slot, the memory card slides firmly into position as well. Unfortunately my baby King Charles Cavalier Spaniel loves its ergonomic look too, and used it as a teething toy, now although it didn't stand up to his grinding teeth, it did protect the memory card, saving my precious back-up of all my photos and allowing me to order a new card reader.
So great product endorsed by me and my Charlie
