They may work on some devices and for the price I think it's worth a try. But they don't work in the devices I've tried them in. The micro card requires what I call a "click". Here, push the card inward to pop it out. This element moves a capture action from the device to a remote location (this element's input slot). My devices do not recognize this deleted snapshot. The snapshot must be taken in the slot of the device itself and not remotely, otherwise it will not recognize a new microcard that you insert. The only way to recognize the new card is to insert and remove this item in the device or restart the device. So be careful. This may or may not work.
