Review on Kiorafoto KHD-SD4: Compact and Lightweight 4-Slot Credit Card Size SD Memory Card Case by Daniel Tonini

Just started using these. The compact size takes up less space than 4 SD cards in separate holders and fits well in camera bags - from pocket in my large DSLR bag to pocket in my much smaller waterproof soap case. notes, but this poses a risk as there is no ejection mechanism. You just grab the ribbed bottom edge of the SD card (you need a good thumbnail) and pull. I had to get used to pulling hard without loosening my grip and letting the card fly. I trained at home to avoid getting into an accident on the field!
