This high-end 4GB Samsung MicroSDHC Plus Memory Card has been vastly improved for handheld devices. Boasting more features than the average micro SD format, this MicroSDHC Plus Memory Card is shockproof and waterproof, to protect it from accidental spills and damage. As well, the MicroSDHC Plus Memory Card is impervious to magnets contained in speakers or other items closeby which can harm the data contained on a card so your data is always protected in any situation. This Class 6 card is also faster than the standard Class 4 microSDs. Faster, better and tougher, the 4GB Samsung MicroSDHC Plus Memory Card provides rugged storage to keep your data safe!
