Everything worked electrically. Unfortunately, the plastic holding the lanyard loop broke off and is no longer in my house. It is also difficult to extract from the port. I bought it to read MicroSDXC cards from my laptop that didn't fit in the internal SD reader with a certain size. It was fine for media access, but I wouldn't recommend it for those who regularly need to remove the card to put it back in the camera. It is too small and prone to breakage and loss. It would probably be good for those using it for semi-permanent use to add storage to their laptop, or as personal removable storage on a work laptop for something like music.
