The product is exactly as advertised. Discounts are genuine. As always SanDisk memory cards have never disappointed me in my previous usage and hope this one too will do the same. I don't doubt the quality of SanDisk cards, my only priority I expect during every purchase is the product genuinity and latest manufactured product, and I am happy to receive what I expected. Am using it in my Sony basic model camera, (snap attached) it works without any issues. I use to record videos too and it is fast enough.
