Summary: This little hippo has great small detail and would easily pass for a cool key chain. The fact that is doubles as a 4G thumb drive is way cool. I got 3 - one for each of my girls. They all love their little animals. I am hoping they make some of these with a larger capacity soon. 4G was huge a few years ago but 16G or more seems to be the standard these days. They all work well, the caps fit snuggley and if you did lose a piece it would be the cap and not the drive.
