The protective case for CF cards and SD (HC) card is a useful supplement for CF and SD & SD (HC) card. The circumferential seal reliable seal against the ingress of dirt and water. The attachment of the memory card by pressing the CF cards provide sufficient protection against falling out of the memory card. The locking mechanism ensures a sealing bias. The aluminum box makes an all around solid impression through the lattice structure as reinforcement. Not cheap, but also an all around felicitous product. Will like to use this again in similar applications.
