I dont understand all the ire. I was perfectly happy with the price for the 5x16gb cards. That was a good deal for those. And if all you need is multiple 16gb cards, not 4k speed for GoPros, it is great.
I'd actually be happy with 4gb or 8gb. My use case is more about having separate cards.
SD cards, like SSDs really don't offer a lot of wiggle room for great deals.
You either pay for performance or not.
