Bests & Worsts Reviews from Amazon

I purchased two of these cards and within two weeks they were both corrupt and unreadable by my computer. I lost over 1000 photos. SanDisk informed me that they don't offer file recovery or reimbursement due to problems with their cards. Completely unhelpful. They DO NOT stand behind their product. Look elsewhere for a reliable card if you value your photos and data. Two weeks was too short to loose everything. Luckily Amazon has great customer service and refunded me.
