I tested everything with a flash drive tester - everything is ok for 32 gigabytes. Of course there are lighter, smaller and faster drives. But it's just fun. They look like keys and are very durable. The contacts are bare, but appear solid. I like the different colors and the flat surface to put a label on. You can't confuse them with many standard types I have.
