Review on High-performance 8GB Sandisk MicroSDHC Memory Card with SD Adapter - Expand Your Device Storage! by Marcus Hargrave

These small 8GB micro cards are great for flashing Nook tablets for rooting and ROM installation and the price was very reasonable. Only $6.50 or so each. That's almost $4 cheaper than what they sell at your local WalMart. Nooks recommend the proprietary SanDisk 4 class and they work flawlessly. The only problem is that the adapter cards only worked once or twice before windows no longer recognized them and I had to be able to format/download files from a PC for it to be worth a star. EDIT: It turns out that the adapters that came with these microSD cards work fine. Something was wrong with my computer, but the adapters have been working great since I've been using the laptop for a bit. So I added the star back. These are the cheapest SanDisk 8GB Class 4 cards I've found from a trusted source and I've not only bought a few more myself but have recommended them to friends.
