The design on these is nice, and the slide feature works well. So far the slide is sturdy enough that it'll lock in place (in or out) with how you want it. The price for the capacity couldn't be beat since this is coming from a reputable company like PNY. I usually use Sandisk. It was worth checking these out based on the other reviews I've read about PNY, and so far so good. It's also nice that the 2-pack came in two different colors to be able to easily distinguish them from the other. Hope this helps. Enjoy! Matthew 7:12
