Great case for iPad
Color: Black
I saw a similar Zugu case for my iPad and almost bought it, but it looked like my iPad might not fit, so I hunted and found this VIKESI case, which cost about 1/3 as much as the Zugu. It's close to perfect. My iPad fits perfectly, and the almost infinite number of angles that it permits, along with magnets to hold it in place make it ideal for working on a desk or in my lap. The only minor downside is that it's on the heavy side, probably because of the magnets. But unless you're travelling with it (I've switched to a small Fire tablet for travel), that won't be an issue. Highly recommended.
