I loved using these microchips back when I had a Blackberry. This is a decent size microchip, but if you are like me and you like to take a lot of pictures you may as well upgrade to something like a 32GB microchip instead. But this brand is very good.
Centon is actually the brand of memory card. "Adapter" is its capability to use a micro SD card in a device that uses a full-size SD card. The larger card in the image above is just a card slot. The mircro SC card slides in at the bottom and then can be operate as a full size card. Hope that's helpful!
