SanDisk16GB MicroSDHC Memory Card

The memory card worked flawlessly in my phone. In installed over 7 GB of music to it when it came, and it has been functioning perfectly since then. It loads a lot faster then the previous off brand card i was using, and hasn't shown any errors. On the downside, The micro sd to sd adapter card that came with it was missing the write protection switch, and does NOT appear to be of the sandisk brand name. Like another purchaser before me, this product came int he small plastic shell case in an envelope, and the shell case was not sealed. I fixed the write protection switch by placing a piece of scotch tape over it, wrapping it around the card and making sure it was on very tight so it doesn't bother my pc. I was then able to transfer files without a problem. i don't know why these come unsealed, but i have a feeling it relates to how they also come damaged / missing pieces.
