I opted for this case due to the price and convenience of it.
A larger case would not fit in my bag however this one does.
My Vita was gathering dust in a drawer before I got this case as I had nowhere else to keep it when I was not playing it. This case kept my Vita dry during the heavy rain and snow during the Autumn/Winter.
The quality of the case is great.
I would and have recommended this case to all Vita owners I know.
