Great, easy way to add a bunch more storage to your gadgets 
figured it would be great for travelling with a bunch of movies on my nexus7 or toss a bunch of psx games on my s7300 or something... For $12 why not right?
Ehhh, not bad, I guess it's a bit more compact and convenient than a thumbdrive dangling from an OTG cable, but still essentially the same principal.
